During the launch from a board, a diver's angular speed about her center of mass changes from zero to 5.10 rad/s in 170 ms. Her rotational inertia about her center of mass is 11.7 kg·m2. During the launch, what are the magnitudes of (a) her average angular acceleration and (b) the average external torque on her from the board?
