Depends on the car and how you are crushing it.
This is actually true. The idea is to lengthen the time that the collision occurs. This sounds counteractive, but it reduces the maximum force that you feel. Theoretically, if a car can double the length of a crash, then the maximum force that people would experience would also be half. So by allowing as much of the car to crush as possible, while still protecting the passengers, makes the cars that much safer. The passenger areas are designed not to crush, for obvious reasons. Why protect a passenger throughout an entire crash to just crush them?
about 5000 thousand mm.
To crush a small to mid size car it takes roughly 2300 psi. If you want to crush a big truck, SUV, or bigger vehicle you will need more than 2400 psi.
double
yes he can if you havent notice in his music video crush he is driving a car
yes, depending on how much force your car has.
No
Earth has much more mass than a car does. Therefore Earth has much stronger gravity.
No. A ping-pong ball, for example, will never dent the car much less crush it because it lacks sufficient mass to develop the required kinetic energy.
Well, when you've finished being crushed, you could NOT say thank you. I wouldn't advise getting into a car crusher, though.
0 work is force times movement.
No. the car runs by how much gas you have and how much power your car engine has.
