Question

In a perfectly inelastic collision between two balls:

a) No changes happen to the internal structure of the balls

b) The total kinetic energy of the balls is conserved

c) The balls have the same velocity after the collision

d) The balls temperature does not change.

Answer 1

Answer:

c) The balls have the same velocity after the collision

Explanation:

In a perfectly inelastic collision between two balls, there is a loss in the maximum kinetic energy of the system and the two ball stick together, and thereby have the same velocity after the collision and also the coefficient of restitution of the two balls is also zero accompanied by a loss in the kinetic energy of the system

Therefore, the correct option is that both balls will have the same (equal) velocity after the collision.
