A classical mechanics problem by Uddeshya Singh

Classical Mechanics Level 2

A solid sphere rolling on a rough horizontal surface with a linear speed v v collides elastically with a fixed, smooth, vertical wall. Find the speed of the sphere after it has started pure rolling in the backward direction.

Hint : Kindly pay attention to elastic collision.

6 v 7 \frac{6v}7 2 v 5 \frac{2v}5 4 v 5 \frac{4v}5 3 v 7 \frac{3v}7
