Question

A bowling ball encounters a 0.760-m vertical rise on the way back to the ball rack, as the drawing illustrates. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 8.21 m/s at the bottom of the rise. Find the translational speed at the top.

0.760m ---------2

Answer 1

In case showing wrong answer please comment below because I have solve by considering ball as a hollow sphere... I question it is not clear if it is solid ball or hollow.

In case it will show wrong, just let me know...I will resolve it fir solid sphere. Thank you.
