A Ferris wheel has radius 5.0 m and makes one revolution in 8.0 seconds. A person weighing 670N is sitting on one of the benches attached at the rim of the wheel. What is the apparent weight (normal force exerted on her with the bench) of the person as she passes during the high-test point of her motion?
