A ball moving with speed v0. experiences a collision with a “running” horizontal flat track Speed of the track v » v0 The deformations of the ball upon impact are elastic. Friction coefficient -u. Angle of incidence - a. When rebounding, the speed of the ball is less than v. Determine the angle of reflection b. The impact time is short. Consider two cases of relative motion of the ball and the track: a) the ball “catches up” with the track; b) the ball moves towards the track.
