Find the magnitudes of her average angular acceleration

Reference no: EM13339568

During the launch from a board, a diver's angular speed about her center of mass changes from zero to 4.50 rad/s in 220 ms. Her rotational inertia about her center of mass is 12.1 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?
