Question

A chemistry student with a mass of 75 kg is riding a steadily moving Ferris wheel. When she is at the top of the Ferris wheel, the normal force from the seat on to her body has a magnitude of 557 N.

a) What is the magnitude of the normal force on her body when she is at the bottom of the Ferris wheel's arc?

913 N was the right answer

b) What would the normal force be on the student at the top of the wheel if the wheel's velocity were doubled?

ANSWER IS NOT 16.75 N OR -16.75 OR 719 N or 23 or -23 i already tried these and got the answer wrong..

Explanation / Answer

I can assureyou the answer is 23N, I have checked it thoroughly. The force centrifugal will just become 4 times to give that answer(assumed g=9.8). The computers answer could be wrong
