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 8.0 s. Assume the merry-go-round is a uniform disk ofradius 1.5 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 torquerequired to produce the acceleration, neglecting frictionaltorque.
___m·N
What force is required at the edge?
___N
