If a trapeze artist rotates once each second while sailing through the air and contracts to reduce her rotational inertia to one-third of what it was, how many rotations per second will result?

physics
If you move your hand inward to be only 0.10 m from the bolt, find the force that you should exert to achieve the same torque.
