Question

In rear-end collision, what happens when both cars are moving in the same way?

1) Both cars will collide
2) Both cars will stop abruptly
3) Both cars will pass each other safely

Answer 1

In a rear-end collision with both cars moving in the same direction, both cars will collide, exchanging momentum while the total momentum of the system remains constant.

Step-by-step explanation:

In a rear-end collision where both cars are moving in the same direction, the outcome is that both cars will collide. This type of collision can be better understood with the principles of conservation of momentum, which states that the total momentum of a closed system remains constant if no external forces act on it. In the case mentioned, car 1 will slow down due to the collision and transfer some of its momentum to car 2, which will speed up. Even though there's an exchange of momentum between the two vehicles, the total momentum of the system consisting of both cars remains constant.
