1. The problem statement, all variables and given/known data 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 567 N. What is the magnitude of the normal force on her body when she is at the bottom of the Ferris wheel's arc? 3. The attempt at a solution This is what I have so far: Top: Ntop + mg = m(v^2/r) Bottom: Nbot - mg = m(v^2/r) This is what I got from the free body diagram. It doenst look right at all to me and I have struggled with this problem for a while. Help! NEW!!! Just added! Part 2: What would the normal force be on the student at the top of the wheel if the wheel's velocity were doubled? I multiplied the acceleration (a = -2.24) by 4 and plugged it into the equations I figured out for the first problem: Top: Ntop - mg = -m(v^2/r) I got 63N. Which is wrong. Any ideas?
