Homework Help: Physics ang. momentum

Posted by Taylor on Monday, December 7, 2009 at 12:29am.

A diver can reduce her moment of inertia by a factor of about 3.5 when changing from the straight position to the tuck position. If she makes 2.0 rotations in 1.5s when in the tuck position, what is the percent change in her kinetic energy as she changes to the straight position??

Please explain to me how to get this problem step by step.
