How do you find the Kinetic Energy of a person spinning on a chair with 2 equal weights on each arm?(adsbygoogle = window.adsbygoogle || []).push({});

A specific problem asks what the change in KE is if he moves his originally extended arms inward.

I tried doing (1/2)(I)(wf)^2 - (1/2)(I)(wi)^2 where wi is initial angular velocity and wf is final angular velocity, but its wrong.

Any help?
