A gymnast flipped in the air with a maximum angular velocity of 6.5 rad/s while maintaining a constant body position. What is the magnitude of the angular impulse (in kg*m^2/s) exerted by the floor on that gymnast when they stuck the landing (w = 0 rad/s) if they had a mass of 53.3 kg and a radius of gyration of 0.8 m?
