A baseball pitcher throws the ball in a motion where there is rotation of the forearm about the elbow joint as well as other mov
ements. If the linear velocity of the ball relative to the elbow joint is 22.3 22.3 m/s at a distance of 0.480 0.480 m from the joint and the moment of inertia of the forearm is 0.550 0.550 kg·m2, what is the rotational kinetic energy of the forearm?
