In the park, a mom pushes tangentially on a hand-drivenmerry-go-round and is able to accelerate it from rest to afrequency of 20 rpm in 10.0 s. Assume the merry-go-round is a uniform disk ofradius 2.0 m and has a mass of900 kg, and two children (each with a massof 20 kg) sit opposite each other on the edge.

Calculate the torque required to produce the acceleration,neglecting frictional torque.
