A playground merry-go-round of radius R = 1.20 m hasamoment of inertia I = 250 kg·m2 and isrotatingat 11.0 rev/min about a frictionless vertical axle. Facingthe axle,a 25.0 kg child hops onto the merry-go-round and managesto sit downon its edge. What is the new angular speed ofthemerry-go-round?
______________ rev/min
