10.) Three children are riding on the edge of a merry-go-round that is a disk of mass 98 kg, radius 1.5 m, and is spinning at 19 rpm. The children have masses of 22.4 kg, 28.4 kg, and 33.4 kg. If the child who has a mass of 28.4 kg moves to the center of the merry-go-round, what is the new magnitude of angular velocity in rpm?    If the child who has a mass of 28.4 kg moves to the center of the merry-go-round, what is the new magnitude of angular velocity in rpm?
