Dad is pushing his son on the merry-go-round in the park. The merry-go-round has a mass of 160 kg and a diameter of 2.40 m; dynamically, it can be treated like a disc. His 35 kg son is sitting 0.80 m from the center of the merry-go-round. If dad pushes with a tangential force of 45.0 N for 1.50 seconds three times, what is the final angular velocity of the merry-go-round, and how fast is his son moving (tangentially) if the merry-go-round starts from rest
