A teenager pushes tangentially on a small hand-drivenmerry-go-round and is able to accelerate it from rest to afrequency of 16.6 rpm in 11.9 s. Assume the merry-go-round is auniform disk of radius 2.58 m and has a mass of 855 kg, and twochildren (each with a mass of 27.3 kg) sit opposite each other onthe edge. Calculate the torque required to produce theacceleration, neglecting frictional torque.
