a student of weight 671 n rides a steadily rotating ferris wheel (the student sits upright). at the highest point, the magnitude of the normal force f with arrown on the student from the seat is 543 n. (a) Does the student feel light or heavy there? (b) What is the magnitude of Fn the lowest point? If the wheels speed is doubled, what is the magnitude FN at the (c) highest and (d) lowest point?"
