Figure P6.59 shows a Ferris wheel that rotates four times each minute and has a diameter of 20.0 m

Figure P6.59

(a) What is the centripetal acceleration of a rider? m/s2

(b) What magnitude force does the seat exert on a 50.0 kg rider at the lowest point of the ride? N

(c) What magnitude force does the seat exert on the rider at the highest point of the ride? N

(d) What force (magnitude and direction) does the seat exert on a rider

when the rider is halfway between top and bottom, going up? NÂ° (measured inward from the vertical)
