Problem 25PE

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 20.0 m/s at a distance of 0.480 m from the joint and the moment of inertia of the forearm is 0.500 kg ? m2 , what is the rotational kinetic energy of the forearm?

Step-by-Step Solution:

Step-by-step solution Step 1 of 2 When the baseball pitcher throws the ball, there is a rotation of forearm about the elbow joint, so the angular velocity of the forearm when he holds the ball, which has a linear velocity of 20.0 m/s, is calculated as, Where, is the linear velocity of the ball, is the distance of ball from the joint. Substitute 20.0 m/s for a nd 0.480 m for . Also the moment of inertia of the forearm is given,
