A child of 44.0 kg takes a ride on a Ferris wheel which rotates four times each minute and consists of a diameter of 20.0 m.
(i) Determine the centripetal acceleration of the child?
(ii) Determine at what force (magnitude and direction) does the seat apply on the child at the lowest point of the ride?
(iii) What force does the seat apply on the child at the highest point of ride?
(iv) At what force does the seat apply on the child if the child is halfway among the top and bottom? (Suppose that the Ferris wheel is rotating clock-wise and the child is moving upward.)
