Question

A circular-motion addict of mass 85 kg rides a Ferris wheel around in a vertical circle of radius 10 m at a constant speed of 6.1 m/s.
(a) What is the period of the motion?
__________s

(b) What is the magnitude of the normal force on the addict from the seat when both go through the highest point of the circular path?
_________N

(c) What is it when both go through the lowest point?
__________ N

Answer 1

speed is 2PIr/T solve for T
normal seat at top=mg-mv^2/r
lowert point mg+mv^2/r
