When a diver gets into a tuck position by pulling in her arms and legs, she increases her angular speed. before she goes into the tuck position, her angular velocity is 5.5 rad/s and she has a moment of inertia of 2.0 kg · m2. once she gets into the tuck position, her angular speed is 11.5 rad/s. determine her moment of inertia when she is in the tuck position. assume the net torque on her is zero?
