A playground merry-go-round made in the shape of a solid disk, hasa diameter of 2.74 m and a mass of353.7 kg. Two children, each of mass30.2 kg, sit on opposite sides at the edgeof the platform. Approximate the children as point masses.

a) What torque is required to bring themerry-go-round from rest to 26 rpm in19.7 s?

b) If two other bigger children are going to push on themerry-go-round rim to produce this acceleration, with what forcemagnitude must each child push?
