A day-care worker pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a spinning rate of 18.2 rpm in 10.0 second. Suppose the merry-go-round is a disk of radius 2.30 meter and has a mass of 870 kilogram, and two kids (each with a mass of 25.2 kilogram) sit opposite each other on the edge. Find the torque required to produce the acceleration? Ignore frictional torque.
