A solid sphere can roll on the smooth surface.

A solid sphere rolling on a rough horizontal surface with a linear speed 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.

A solid sphere is rolling purely on a rough horizontal surface (coefficient of kinetic friction =mu ) with speed of centre =u . It collides inelastically with a smooth vertical wall at a certain moment, the coefficient of restituting being (1)/(2) . The sphere will begin pure rolling after a time.
