A playground merry-go-round of radius R = 2.17 m has a moment of inertia of I = 280 kg * m2 and is rotating at 13.0 revolutions/min about a frictionless vertical axle. Facing the axle, a 21.8 kg child hops onto the merry-go-round and manages to sit down on its edge. What is the new angular speed (in revolutions per minute) of the merry-go-round? Do not enter units
