Problem
A playground merry-go-round rotates steadily at 15rpm. The brakes are applied so that it comes to rest in 40s with uniform angular deceleration. A child is seated 2.0m from the axis.
(a) Calculate the magnitude of the angular deceleration.
(b) Determine the linear distance travelled by the child while the merry-go-round is slowing down.
