A carousel has a radius of 1.60 m and a moment of inertia of 118 kg • m². A girl of mass 48.0 kg is standing at the edge of the carousel, which is rotating with an angular speed of 3.10 rad/s. Now the girl walks toward the center of the carousel and stops at a certain distance from the center d. The angular speed of the carousel is now 5.4 rad/s. How far from the center, in meters, did the girl stop? Both the girl and the carousel will contribute to the moment of inertia of the rotating system.
