A bowling ball encounters a 0.760 mvertical rise on the way back to the ball rack, as the drawingillustrates. Ignore frictional losses and assume that the mass ofthe ball is distributed uniformly. The translational speed of theball is 4.00 m/s at the bottom of therise. Find the translational speed (in m/s) at the top.
