A gymnast is performing a giant swing on the high bar. In a simplified model of the giant swing, treat the gymnast as a rigid object that swings around the bar without friction. With what angular speed should he be moving at the bottom of the giant swing in order to make it all the way around? The distance from the bar to his feet is 5.16 m and his center of gravity is 2.58 m from his feet. in rad/s?
