Q1. A Ferris wheel is a vertical, circular amusement ride with radius 6 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates at the constant rate, going around once in 6.4 s. Consider a rider whose mass is 70 kg.
Q2. Assume a satellite is in a circular orbit 4.125 Earth radii above the surface of the Earth (5.225 Earth radii from the center of the Earth). By how much does it have to increase its speed in order to be able to escape Earth?
Where is center of mass of the system
A crate of 30.2- tools rests on a horizontal floor. You exert a regularly increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 319. After that you must reduce your push to 227 to keep it moving at a..
