Exercise 8

A bowling ball with a diameter of 21.6 cm is rolling down a level alley surface at 12.7 m/s without slipping. Assume the ball is uniform and made of plastic with a density of 800 kg/m 3. (a) What is the angular speed of tire ball (b) Calculate the speed (relative to the alley surface) of a point on top of the ball directly above the contact point on the floor. (c) What is the ball's linear kinetic energy (d) If it now starts to roll up a 30° incline, how far up the incline will it travel before it stops
