What is the new angular velocity in rpm

Reference no: EM13543936

Three children are riding on the edge of a 1.60-m-radius, 100 kg merry-go-round, spinning at 20.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the child with a mass of 28.0 kg moves to the center of the merry-go-round, what is the new angular velocity in rpm?
