Question:A bumper car is moving at 5 mph. It crashes into another bumper car. What happens to the energy of the bumper car?
Answer: The bumper cars. This law, the law of interaction, says that if one body exerts a force on a second body, the second body exerts a force equal in magnitude and opposite in direction on the first body. It's the law of action-reaction, and it helps to explain why you feel a jolt when you collide with another bumper car.The collision between two bumper cars can redistribute their total energy, but it can't change that total. Unfortunately, the collision between bumper cars can and does grind up some of their ordered energy into thermal energy.
Explanation: When a car hits something at a low speed, the bumper will press backward to use the crumple zone to soften the impact as the foam and fenders absorb the energy.More severe impacts will cause the bumper to split open, dent, or crumple inward. An impact can also damage the hooks that attach the bumper to your car. In this situation, one end of the bumper may sag awkwardly or drag along the ground. If both hooks break, your entire bumper assembly may simply fall off.
