A bowling ball with a diameter of 21.9cm is rolling down a level alley surface at 12.1m/s without slipping. Assume the ball is uniform and made of plastic with a density of 850kg/m3 . What is the angular speed of the ball? Calculate the speed (relative to the alley surface) of a point on top of the ball directly above the contact point on the floor. v=? What is the ball's linear kinetic energy? K=? If it now starts to roll up a 30 incline, how far up the incline will it travel before it stops?
d=?
