Problem
We spin a rigid ball in the air with angular velocity ω high enough parallel with the ground. After that we let the ball fall from height h0 onto a horizontal surface. It bounces back from the surface to height h1 and falls to a slightly different spot than the initial spot of fall. Determine the distance between those two spots of fall onto ground, given the coefficient of friction f between the ball and the ground is small enough.
