A playground merry-go-round of radius R = 1.80 m has a moment of inertia I = 260 kg · m2 and is rotating at 11.0 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?
rev/min
