A bowler projects an 8-in.-diameter ball weighing 12 lb along an alley with a forward velocity v, of 15 ft/s and a backspin w, of 9 rad/s. Knowing that the coefficient of kinetic friction between the ball and the alley is 0.10, determine (a) the time t, at which the ball will start rolling without sliding, (b) the speed of the ball at time ,, (c) the distance the ball will have traveled at time t,.
