A playground merry-go-round of radius 2.00 m hasamoment of inertia I = 295kg·m2 and is rotatingabout a frictionlessvertical axle. As a child of mass 25.0 kgstands at a distance of1.00 m from the axle, the system(merry-go-round and child) rotatesat the rate of 15.0 rev/min. Thechildthen proceeds to walk toward the edge of the merry-go-round.Whatis the angular speed of the system when the child reachestheedge?
1 rad/s
