Rail Guns the Unrealized Killer

In the movie the "Eraser" Arnold Schwarzenegger is a Witness Protection Agent. In the movie a company has developed a portable  railgun and is planning on selling it to foreign powers. An employee, Lee Cullen, of the company decides to turn them into the government for treason. Following the events of the movie Arnold eventually gets ahold of one of the railguns. Now the question is what would have happened when he fires the rail gun.
Well when he first fires the gun the recoil caused by firing it produces 26549 kilometers a second of force which would slice through Arnold killing him instantly.



The victim on the other hand receives a much lesser force of only 3745 kilometers a second. Which is still enough to kill him instantly. In conclusion the railgun in this movie is simply unrealistic because it would kill any person instantly.

  1. Don't confuse velocities with forces. What you have calculated are recoil velocities. You could use the impulse equation we learned this week to calculate the average force if you knew how long these "collisions" lasted, but that's not what we're doing right now. You also made a math error in calculating the velocity of the victim. It should have been 10 times higher than what you calculated.
