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 3.95 m/s at the bottom of the rise. Find the translational speed at the top.

(a) Number A man holds a 155-N ball in his hand, with the forearm horizontal (see the figure). He can support the ball in this position because of the flexor muscle force M. which is applied perpendicular to the forearm. The forearm weighs 22.3 N and has a center of gravity as indicated. Find (a) the magnitude of M and the (b) magnitude and (c) direction (as a positive angle counterclockwise from horizontal) of the force applied by the upper arm bone to the forearm at the elbow joint.
