A bowler throws a bowling ball of radius R = 11 cm down a lane. The ball slides on the lane with initial speed vcom,0 = 6.5 m/s and initial angular speed ?0 = 0. The coefficient of kinetic friction between the ball and the lane is 0.27. The kinetic frictional force fk acting on the ball causes a linear acceleration of the ball while producing a torque that causes an angular acceleration of the ball. When speed vcom has decreased enough and angular speed ? has increased enough, the ball stops sliding and then rolls smoothly.

(a) What then is vcm in terms of ??

_______m·?

(b) During the sliding, what is the ball's linear acceleration?

________m/s2

(c) During the sliding, what is the ball's angular acceleration?

_________rad/s2

(d) How long does the ball slide?

_________s

(e) How far does the ball slide?

_________m

(f) What is the speed of the ball when smooth rolling begins?

__________m/s
