Two children standing on opposite sides of a merry-go-round are trying to rotate it. They each push in opposite directions with forces of magnitude 10.0 N.

a) If the merry-go-round has a mass of 180 kg and a radius of 2.0 m, what is the angular acceleration of the merry-go-round? (Assume the merry-go-round is a uniform disk).

b) How fast is the merry-go-round rotating after 4.0s?
