Torque on a Merry-Go-Round
A) 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 18.7 rpm in 11.3 s. Assume the merry-go-round is a disk of radius 2.60 m and has a mass of 820 kg, and two children (each with a mass of 25.7 kg) sit opposite each other on the edge. Calculate the torque required to produce the acceleration, neglecting frictional torque.
B) What force is required?
