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