During launch from a diving board, a diver's angular velocity abouther center of mass cahnges from 0 to 5.40 rad/s in 180m/s. Her rotational inertia about her center of mass is 10.5kgm2. During the launch, find her average angularacceleration, the average external torque exewrted on her by theboard, and the total number of degrees she rotates.
