What is the new angular speed of the merry-go-round

Reference no: EM13672148

A playground merry-go-round of radius R = 2.00 m has a moment of inertia I = 245 kg m² and is rotating at 9.0 rev/min about a frictionless vertical axle. Facing the axle, a 27.0 kg child hops onto the merry-go-round and manages to sit down on its edge. What is the new angular speed of the merry-go-round?
