A playground merry-go-round of radius R = 2.20 m has a moment of inertia I = 255 kg ·m2 and is rotating at 8.0 rev/min about a frictionless vertical axle. Facing the axle, a 22.0-kg child hops onto the merry-go-round and manages to sit down on the edge. What is the new angular speed of the merry-go-round? 6.72 There is no external torque applied to the child/merry-go-round system. What quantity will be conserved in this case? rev/min Need Help?
