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 20.4 rpm in 11.0 s. Assume the merry-go-round is a disk of radius 2.34 m and has a mass of 700 kg, and two children (each with a mass of 26.8 kg) sit opposite each other on the edge. Calculate the torque required to produce the acceleration, neglecting frictional torque. what force is required?
