(10%) Problem 9: Three children are riding on the edge of a merry-go-round that is a disk of mass 96 kg, radius 1.2 m, and is spinning at 19 rpm. The children have masses of 21.2 kg, 27.2 kg, and 32.6 kg. Randomized Variables M=96kg m1=21.2kg m2=27.2kg m3=32.6kg r=1.2m f=19rpm A If the child who has a mass of 27 2 kg moves to the center of the merry-go-round, what is the new magnitude of angular velocity in rpm
