Question

You are given a problem in which you are told the collision is perfectly inelastic. What does this tell you?

A. After the collision, one of the objects remains motionless.

B. The two objects swap velocities during the collision.

C. The two objects emerge from the collision with the same velocity.

D. After the collision, both objects are motionless.

Answer 1

In a perfectly inelastic collision, the two objects stick together, so answer (C) looks like the best choice.
