Question

(10%) Problem 8: Three children are riding on the edge of a merry-go-round that is a disk of mass 98 kg, radius 1.9 m, and is spinning at 16 rpm. The children have masses of 204 kg, 28.4 kg, and 342 kg Randomized Variables M = 98 kg mi -204 kg m2 = 28.4 kg m3 34.2 k r=1.9 m f= 16 rpm CIf 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?
