Determine the final angular speed of the merry-go-round

Reference no: EM13265843

a rotating merry-go-round is essentially a disk with mass of 250 kg an radius of 2.5m, rotating at one rev. every 5sec. after gently places his small son ( m=15kg) on the edge of merry-go-round without slipping. Determine the final angular speed of the merry-go-round/son combination. hint the son's moment of inertia is just I=mr^2
