A bowling ball of mass m and radius R is released so that at the instant it touches the floor it is moving horizontally with a speed v0 and is not rotating. It slides a distance s1 in time t1 before it begins to roll without slipping. If μk is the coefficient of kinetic friction between the ball and the floor, find s1, t1 and the final speed of the ball, v1. What is the ratio of the final kinetic energy to the initial kinetic energy of the ball?
