A carousel has a radius of 1.65 m and a moment of inertia of  114 kg · m2.  A girl of mass 42.0 kg is standing at the edge of the carousel, which is rotating with an angular speed of 3.30 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 5.2 rad/s. How far from the center, in meters, did the girl stop?
