Angular velocity, Physics

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