2 Fast 2 Furious 2 Marginal

2 Fast 2 Furious 2 Marginal
2 Fast 2 Furious was a sequel to the movie The Fast and Furious. Brian O’Conner (Paul Walker) and Roman Pearce (Tyrese Gibson) perform fast street racing as well as incredible stunts. Some insane stunts are even hard to believe, so I will be analyzing the physics behind a stunt scene in 2 Fast 2 Furious.
The scene I will be analyzing consists of Brian and Roman jumping a 1969 Chevy Camaro into a motor yacht. The two accelerate, launch off a jump, and then proceed through the air with unorthodox trajectory and land nearly perfect on the rear of the large vessel. I will be questioning the impulse of their sudden stop as they collide with the yacht and the correct distance they should have travelled given their velocity and estimated height.
A tremendous amount of impulse should have been exerted as this collision happened. Impulse is equivalent to force multiplied by the total time of the event taking place. (I=F(t2-t1)). The event of the car stopping was nearly instantaneous; it will be given an event time of .5 seconds. To find the force of the car, we take the total mass and multiply it by the total acceleration. A 1969 Camaro has a mass of 3,135 lbs and the driver and passenger both appear to be in-shape, adult males averaging 180 lbs each; this is a total of 3,495 lbs.  The motor yacht was moving at cruising speed which is around 12 mph. The acceleration was 120 mph to 12 mph. This is a total deceleration of 108 mph. Converting the units to kg (Kilograms) and m/s (meters per second), we get 1585.3 Kg and 48.28 m/s. 1585.3 kg x 48.28 m/s =76,538.28 N (Newtons). Impulse equals force multiplied by total time. 76,538.28 N x .5 s = 38,269.14 N-s (Newton seconds).
The jump itself was questioned by Roman as Brian sped to 120 mph and launched both of them off of the ramp. Since Roman questioned the jump, I’ll crunch the numbers for him to see if his fear was justifiable. The ramp, that the Camaro jumped, is estimated to be three meters long and one meter high. Using trigonometry , three is our adjacent side (b) and one is our opposite side (a). To find the angle needed (A), we use the equation Tan^-1 (⅓). Our result is 18.43 degrees. We can then make a larger triangle using the total height of the car (5.19 m) and the takeoff angle (18.43 degrees). We find the angle needed for our calculation (B) by adding the takeoff angle (A) plus our ninety degree angle (C) (18.43+90=108.43). We then subtract the given number from 180 degrees, leaving us angle B; 71.57 degrees. Our opposite side(a) is 5.19 m, our angle A is 18.43 degrees, and our angle B is 71.57 degrees. By plugging this information into the equation (c=a sin C/ sin A) [5.19 sin (71.57)/ sin(18.43)] we result in the adjacent side length (b); 15.57 m. Since this is a triangle of only half of the distance the Camaro travelled, we multiply this number by two. Our final distance is 31.14 meters (102.16 ft).

In the cut of the car midair between the bank and the yacht, we have an accurate estimate of the distance between the car and vessel. A 1969 Chevy Camaro is 15.5 ft in length. There were exactly four car lengths between the end of the ramp (bank of the shore) and the rear of the yacht. Multiplying 4 car lengths by 15.5 ft (length of the Camaro) we have a total distance of 62 ft.
Taking into consideration that the yacht was moving away from the bank and Brian landed the Camaro on the top bridge of the boat, we’ve come to the conclusion that the scene is possible and the jump would have had a trajected landing on the yacht. Given Roman’s perspective, he seemed afraid when in fact Brian would have made the jump. But given the thought of jumping over 100 ft while travelling at a velocity of 120 mph, Roman had every right to be scared.

Contact

     According to the twin paradox, the main event in the movie Contact was backwards. The main character, Ellie, experiences a time of 18 hours in which she meets her alien father. All of this takes place in about 2 seconds of Earth time.
     If the movie was correct and followed the twin paradox, Ellie would have felt like she traveled for a relatively short period of time (a few seconds, maybe even a few minutes if she's lucky). All of this would be happening on a very large time frame on Earth, Earthlings would experience time of a few hours or even days as Ellie flew through space and back. But this is movie physics I am explaining.
     If the movie was realistic, Ellie would have most likely died from either boredom or starved to death on the space ship during her venture to Vega. If she somehow survived, she'd come back to say I told you. But she'd find everyone, that cared for her and for her mission, dead or nearly dead.

Fat Man and Little Boy Logistics

     "Fat Man and Little Boy" not only illustrates the motives for creating weapons of mass destruction, but it also condemns the entire idea of the weapons. "Gojira" illustrates the mutually negative impacts of such weapons of mass destruction as the monster itself was disturbed by the weapons.

     During the initial hypothesizing of creating the "device", scientists from "Fat Man and Little Boy" had positive motives for creating the weapon. The only reason for positiveness in such a dark subject was to prevent further life from being lost on the American side. Later information contradicts the previous thoughts of the creation of the weapon as the scientists are leaked information of the intentional use of the bomb. The motive of the US Government was to take a large amount of human life in an inhumane way to prevent further life from being lost on the US's side. During the resolution, many of the scientists disagreed with the creation and even the idea of such a weapon of mass destruction. Oppenheimer even publicly refused to support the creation of such a monstrous creation.

     "Godzilla" was a creature that was disturbed by the weapons of mass destruction, which I find ironic that the monster was inspired by the idea of nuclear weapons, which in themselves are a monster. Godzilla was deemed indestructible by a scientist because of its ability to resist nuclear bombs that initially disturbed it. Another scientist, Serizawa, creates the "Oxygen Destroyer", a device that removes all oxygen surrounding it. The device is fairly inhumane but proves to be the only fighting chance the people of Japan, and possibly the world, have against this creature. Serizawa refuses to use his creation as it is morally wrong to him but as he sees the world around him crumbling, his thoughts are altered. In the resolution, Serizawa uses the device and engages "Godzilla", but he takes his own life during the process as he doesn't want the knowledge of such a monstrous creation circulating.

     In both films, the scientists are faced with a test of justice behind the motives driving them to create these weapons of mass destruction. In both films, the motives are not just, but ironically they are carried out in the end and the weapons were created for better or for worse.

Global Warming

     Global warming used to be a myth, and inexplicably continues to be to some people. The facts are global warming is happening and us humans have contributed to it. CO2 (Carbon Dioxide) is one of the most important contributors to global warming as it acts as a global blanket and traps heat within the Earth's atmosphere. Recently, there has been an astonishing discovery made by NASA satellites.

     El Niños are a major shift in Earth's patterns due to changes in oceans and atmospheres. During this year (2017) the world is experiencing an El Niño pattern. Typically during these patterns, Earth experiences higher CO2 emissions due to lower plant life which is caused by less rainfall. This explains a natural process of global warming without human interference.

     A satellite launched in 2014 was not planned for the event it captured, it happens by coincidence that it was in the perfect point of capture. It captured the phenomenal event of the Pacific Ocean giving off CO2 shortly before surrounding areas released CO2. This once again proves that global warming occurs without human interference deeming it a natural global event.

     Humans have had an adverse effect on global warming by giving off unnatural levels of CO2. The same satellite has picked up higher CO2 levels over cities and highly populated areas. As more CO2 rises into the atmosphere, it simply accelerates the process of global warming.

     As we might all want to prevent any unnecessary accelerations in global warming, I think the human species should not put unnatural amounts of CO2 into the atmosphere as we are literally asking for an expedited death.

     My sources have been thought to be reputable as NASA's website has a .gov suffix. I only used the projections and data from Live Science, which was NASA's data since they had the only satellite capable of retrieving such data from Space at that specific place and time.

Ant Man

     As we all know, Ant-Man packs a rather powerful punch for his size, but a few things don't quite make sense. Ant-Man appears to have the strength of a regular human while he is in his microscopic ant sized form. Simple scaling rules would prove that he would have insanely inhuman strengths when he is in the shape of a normal human being because he packs such a whopping punch as an insect sized man.
     The Physics of Superheroes proves a valid point through the qutoe: "Why do you have the strength that you do, such that you can easily lift a 20-pound object, but struggle with one weighing 200 pounds and can not possibly lift 2,000 pounds?" The scaling of Ant-Man's strength is flawed. When in "Ant sized form" Ant-Man is 0.01x his normal size, meaning his strength would be multiplied by the same reduced amount. Ant-Man cannot easily pick up 2000 lbs when he is normal but can seem to move a 20 lbs object with ease in micro form. He can even move humans by hitting them with his "tiny" punches.
     The fulcrum inside of the human arm is placed very specifically to give us the best advantage to speed and strength for the size of the muscle. Granted if the point of contact of muscle and bone was moved away from the fulcrum, any human could have inhuman strength. This reduces the speed achieved by human muscles but increases the strength. If you move towards the fulcrum the results are the opposite. If Ant-Man had a muscle much farther away from the fulcrum in his arms (elbow and shoulder) he would be able to lift items much heavier then himself. With this being said he would not be able to move them as quickly or efficiently and would look like a total freak, which in the movie he appears to be normal.
     While Ant-Man appears to be a hero to us "The People", he is an abomination to scaling physics. One cannot possibly change the strength of themselves with scaling alone, as Ant-Man was able to lift what would be 2,000 lbs as a regular human while in his ant form.

Armageddon Mission

In the movie Armageddon, the team uses a nuclear blast that supposedly separated a dooms-day sized asteroid. I believe I have found a much safer and more effective way of dealing with an asteroid of this size.

In a certain scenario of finding an asteroid that is on a collision path with Earth, I estimate a time span of 50 years or more of warning. At the minimum of 50 years, us humans would have time to prepare for this event.

Particle Accelerators are an extreme advance in modern science, they take particles and accelerate them to nearly the speed of light. In certain P.A. units, they are set up to create collisions with counter-rotating particles. The biggest P.A. is 17 miles long! When a single collision takes place (2,000-3,000 protons), the energy to melt 1,100 lbs of copper is produced. A current particle colliding machine is capable of producing 600 million collisions a second. The conditions inside of a particle accelerator are space like.

How does the particle accelerator have anything to do with the asteroid?

I propose that mankind develop a particle accelerator that collides atoms in space. Theoretically we can make a section of the accelerator completely open since the conditions inside are the same as space. Create a collision point in the middle of the large gap of the machine.

As the asteroid hurdles towards us, Earthlings would create and place this machine in space directly on the collision course. Since an object in motion stays in motion in space, we would spin this large machine in a rotating manner, such that the particles are able to cover an area wider then the asteroid. Assuming this would take, at the most, 40 years to create and place in space, we would have 10 years to begin accelerating particles and have an adequate amount of particle collisions (>,=600 million) as the asteroid gets near.

As the particle collisions are consistently happening and expelling an enormous amount of energy around the entirety of the asteroid as it passes through the collision field that is constantly rotating, the asteroid would be nearly vaporized as the collisions break apart the asteroid into infinite particles of different elements and space rock (Assuming the initial makeup of the asteroid was iron). As the large cloud of space rock (formally an asteroid) approaches Earth's atmosphere, the enormous amount of bits of asteroid will be burned up in Earth's atmosphere.

The particle collisions actually alter the makeup of the atoms it collides with. If the asteroid was made of iron, it would be collided and the outcome would be several, lighter density, elements. Lighter density would allow the substance to be burned up easier in the atmosphere.
