Question

You carefully place a small rubber ball (mass m) on top of a much bigger basketball (mass M), and drop these from some height h. What is the velocity of the smaller ball after the basketball hits the ground, reverses direction, and then collides with the small rubber ball?

Answer 1

Answer:

3v

Explanation:

A small rubber ball of mass m which is place at top of a bigger basket ball of mass M. These two balls are dropped from the same height h.

The velocity of the smaller ball will be 3v when the basketball hits the ground, reverses direction, and then collides with the small rubber ball.

Thus the answer is 3v.
