Problem
Three children A, B and C are sitting on a merry-go-round that is rotating in a horizontal circle. Their seats are at radial distances of 1.0m, 1.5m and 2.0m respectively from the centre. The platform makes one complete revolution in 12s.
(a) Calculate the speed of each child.
(b) Arrange the three children in order of increasing speed.
(c) Will any of the three children be in a non-uniform circular motion? Give a reason for your answer.
