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 17.1 m/s at a distance of 0.500 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? rotational kinetic energy:

Expert Solution
Step 1

Given:

The linear velocity of the ball relative to the joint is 17.1 m/s.

The distance of the ball from the joint is 0.5 m.

The moment of inertia of the forearm is 0.5 kg.m2.
