A circular-motion addict of mass 83.0 kg rides a Ferris wheel around in a vertical circle of radius 11.0 m at a constant speed of 6.10 m/s. (a) What is the period of the motion? What is the magnitude of the normal force on the addict from the seat when both go through (b) the highest point of the circular path and (c) the lowest point?

1 answer

centripetal force is ... m v^2 / r

a) (2 π r) / 6.10 m/s

b) m [g - (v^2 / r)]

c) m [g + (v^2 / r)]
