A woman stands at the edge of a carousel that is rotating without friction at 0.80 rad/s. The carousel has a radius of 2.0m and a moment of inertia of 600 kg m2. The woman can be treated as a particle of mass 50 kg. The woman walks to the center of the carousel. What is now the angular speed of the carousel?
