# Question

A bowling ball with a radius of 15.0 cm travels down the lane so that its center of mass is moving at 3.60 m/s.

The bowler estimates that it makes about 7.50 complete revolutions in 2.00 seconds. Is it rolling with-out slipping? Prove your answer, assuming that the bowler’s quick observation limits answers to two significant figures.
