Three children are riding on the edge of a mcrry-go-round that is a disk of mass 96 kg, radius I. 9 m, and is spinning at 2! rpm. The children have masses of20.4 kg, 28 kg, and 33. 8 kg Randomized Variables M: 96 kg m; = 20.4 kg \"12:23 kg M} 2 53.8 kg r= 9111 .r'=2!rpm .- a. If the child who has a mass of 28 kg moves to the center of the merry-go-round, what is the new magnitude of angular velocity in rpm? 1
