1. A Ferris wheel at a carnival has a radius of 8 m and turns so that the speed of the riders is 11 m/s.
(a) What is the magnitude of the centripetal acceleration of the riders?
(b) What is the magnitude of the net force is required to produce this centripetal acceleration for a rider with a mass of 65 kg?
2.Two 325-kg masses (722 lb) are separated by a distance of 6 m. Using Newton's law of gravitation, find the magnitude of the gravitational force exerted by one mass on the other.
3.The acceleration of gravity at the surface of the moon is approximately 1/6 that at the surface of the Earth (9.8 m/s2). What is the weight of an astronaut standing on the moon whose weight on Earth is 180 lb?
