A carousel has a radius of 3.0 m and a moment of inertia of 600 kg.m2. When a 20 kg child starts to move from the center of the carousel to the tip, the carousel rotates with an angular velocity of 0.80 rad / s. When the child reaches the end of the carousel, what is the angular velocity of the carousel?

A playground carousel is free to rotate about its center on frictionless bearings, and air resistance is negligible. The carousel itself (without riders) has a moment of inertia of 125 kg · m2. When one person is standing on the carousel at a distance of 1.5 m from the center, the carousel has an angular velocity of 0.6 rad/s. However, as this person moves inward to a point located 0.918 m from the center, the angular velocity increases to 0.8...
