A baseball pitcher throws the ball in a motion where there is rotation of the forearm about the elbow joint as well as other movements. If the linear velocity of the ball relative to the elbow joint is 18.3 m/s at a distance of 0.500 m from the joint and the moment of inertia of the forearm is 0.450 kg·m2, what is the rotational kinetic energy of the forearm?
