A bowlerthrows a bowling ball of radius R = 11 cm along a lane.The ball(Fig. 11-37) slides on the lane with initial speed vcom,0= 6.3 m/sand initial angular speed Ï0 = 0. The coefficientof kineticfriction between the ball and the lane is 0.12. Thekineticfrictional force k acting on the ball causes a linearaccelerationof the ball while producing a torque that causes anangularacceleration of the ball. When speed vcom has decreasedenough andangular speed Ï has increased enough, the ball stopssliding andthen rolls smoothly. During the sliding, what are theball's (a)linear acceleration and (b) angular acceleration? (c)How long doesthe ball slide? (d) How far does the ball slide? (e)What is thelinear speed of the ball when smooth rolling begins?Note that theclockwise direction is taken as negative.
