A playground merry-go-round of radius 2.00 m has a moment ofinertia I = 255 kg·m2 and is rotating about a frictionless verticalaxle. As a child of mass 25.0 kg stands at a distance of 1.00 mfrom the axle, the system (merry-go-round and child) rotates at therate of 12.5 rev/min. The child then proceeds to walk toward theedge of the merry-go-round. What is the angular speed of the systemwhen the child reaches the edge?
_____ rad/s
