A 4.5--diameter merry-go-round is rotating freely with an angularvelocity of 0.81 . Its total moment of inertia is 1760 . Fourpeople standing on the ground, each of mass 65 , suddenly step ontothe edge of the merry-go-round. What is the angular velocity of themerry-go-round now?

A 3.0m diameter playground merry-go-round has a rotational inertia of 120 kg-m^2 and is spinning at 0.50 rev/s. What is the rotational kinetic energy of the merry-go-round? If four 25-kg children sit suddenly on the edge of the merry-go-round, what will be the new angular speed of the merry-go-round? With the children sitting on the edge of the merry-go-round what is the new angular kinetic energy of the merry-go-round? Was rotational kinetic energy "gained" or "lost" when the children jumped on the merry-go-round?

A playground merry-go-round of radius R = 1.87 m has a moment of inertia of I = 287 kg * m2 and is rotating at 10.8 revolutions/min about a frictionless vertical axle. Facing the axle, a 28.7 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?
