A playground merry-go-round of radius 2.00 m has a moment ofinertia I = 300kg·m2 and is rotating about a frictionlessvertical axle. As a child of mass 25.0 kg stands at a distance of1.00 m from the axle, the system (merry-go-round and child) rotatesat the rate of 15.0 rev/min. The childthen proceeds to walk toward the edge of the merry-go-round. What is the angular speed of the system when the child reaches the edge?
