PhysicsEasysingle choice

A solid sphere moves on a horizontal surface, performing pure rolling motion, with speed $v_{0} .$ It collides with a smooth vertical wall elastically. the velocity at which it again performs pure rolling, is

Options:

Answer:

Solution:

COAM

$M v_{0} R - \frac{2}{5} M v_{0} R = \frac{7}{5} M v R$

$v = \frac{3}{7} v_{0}$
