A student of weight 660 N rides a steadily rotating Ferris wheel (the student sits upright). At the highest point, the magnitude of the normal force FN on the student from the seat is 551 N.
a) Does the student feel "light" or "heavy" there?
heavy
light
b) What is the magnitude of FN at the lowest point?
c) If the wheel's speed is doubled, what is the magnitude of FN at the highest point?
d) What is the magnitude of FN at the lowest point under the same conditions as in (c)?
