A plank of mass M rests on a smooth horizontal plane A sphere of mass m and radius r is paced on the rough upper surface of the plank and the plank is suddenly given a velocity v in the direction of its length Find the time after which the sphere beings pure rolling if the coefficient of friction between the plank and the sphere is u and the plank is sufficiently long
