A passenger with mass 85 kg rides in a Ferris wheel. The seats travel in a circle of radius 35 m . The Ferris wheel rotates at constant speed and makes one complete revolution every 25 s . 1) Calculate the magnitude of the net force exerted on the passenger by the seat when she is one-quarter revolution past her lowest point. 2) Calculate the direction of the net force exerted on the passenger by the seat when she is one-quarter revolution past her lowest point.
