1. Mikal's leg angularly accelerates 3000/s2 around her hip joint during a roundhouse kick in the transverse plane. The moment of inertia of her leg around the axis of rotation for this kick is 0.75 kgm2. How large is the torque that produces this acceleration?

2. Caleb is driving a golf ball off the tee. His downswing takes 0.50 s from the top of the swing until ball impact. At the top of the swing, the club's angular velocity is zero; at the instant of ball impact, the club's angular velocity is 30 rad/s. The swing moment of inertia of the club about the grip is 0.220 kgm2. What average torque does Caleb exert on the golf club during the downswing?
