A baseball pitcher pivots his extended arm about his shoulder joint, applying a constant torque of 197 N · m for 0.24 s to his arm, which has a moment of inertia of 0.40 kg · m2.

(a) Find his arm's angular acceleration and final angular velocity, assuming it starts from rest.

(b) Find the final speed of the ball, relative to his shoulder, which is 0.73 m from the ball.
