Consider a satelite in a low altitude orbit around the earth. the gravitational acceleration felt by the satelite is very close to the gravitational acceleration felt by objects on the surface of the earth: 9.8m/s^2 and is directed toward the center of the earth. the orbit of the satelite is a perfect circle centered on the center of the earth. there are no forces other than gravity acting on the satelite. find how fast the satelite must be moving in order to remain in orbit. explain all steps you take in order to carry out this calculation using concepts we have defined in this class.
