Document Summary
; since initially the ball is not rotating. Assume that the cue stick strikes the ball horizontally with a force of constant magnitude. Then the magnitude of the change in linear momentum of the ball is given by f t. = p = p; since the initial momentum is zero. For the ball to roll without slipping we need v= r . X = i mr is the condition for rolling without sliding from the s61. R: a bowler throws a bowling ball of radius r=11. 0 cm down the lane with initial speed v0=8. 50 m s. The ball is thrown in such a way that it skids for a certain distance before it starts to roll. It is not rotating at all when it first hits the lane, its motion being pure translation. The coefficient of kinetic friction between the ball and the lane is 0. 210. N=mg , where m is the mass of the bowling ball.
