A 25.0 kg child sits at the outer edge of a merry-go-round that has mass 200 kg and radius 4.0 m and is rotating at 1.0 rad/s. a. If the child moves to the center of merry-go-round, what is the resulting angular speed? Treat the merry-go-round as a solid cylinder. b. What is the change in the kinetic energy of the system? c. Is this “collision” elastic, inelastic or an explosion?
