A teenager pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 12 rpm in 10.0 s. Assume the merry-go-round is a uniform disk of radius 2.1 m and has a mass of 700 kg, and two children (each with a mass of 23 kg) sit opposite each other on the edge.
Part A Calculate the torque required to produce the acceleration, neglecting frictional torque. Express your answer using two significant figures.
Part B What force is required at the edge? Express your answer using two significant figures.
