Consider the father pushing a playground merry-go-round. He exerts a force of 250 Newton at the edge of the 50 kilogram merry-go-round, which has a 1.50 meter radius. Determine what the angular acceleration produced

(a) when no one is on the merry-go-round and

(b) when an 18 kilogram child sits 1.25 meter away from the center. Consider the merry-go-round itself to be a uniform disk with negligible retarding friction.
