During the launch from a board, a diver's angular speed about her center of mass changes from zero to 6.90 rad/s in 310 ms. Her rotational inertia about her center of mass is 12.0 kg · m2. (a) During the launch, what was the magnitude of her average angular acceleration? rad/s2 (b) During the launch, what was the magnitude of the average external torque on her from the board? N.m
