Aplayground merry-go-round has a mass of 115 kg and a radius of 2.50 m and it is rotating with an angular velocity of 0.520 rev/s. the merry-go-round is a solid disk, and the moment of inertia is = 1/2 mr2. a 23.5 kg child is initially at rest, he then gets onto the merry-go-round by grabbing its outer edge. the child can be treated as a point mass located at the outer edge of the merry-go-round. his moment of inertia is mr2. after this rotational collision, the merry-go-round and the child have a commen final angular velocity (which is different from the merry-go-round's initital angular velocity). (e) what is the final angular velocity in rad/s after the child gets on?
