A satellite of mass m is in a circular orbit around the Earth (mass M) at a distance R from the center of the earth. (a) What is the speed of the satellite? (b) From your answer in part (a), how long does it take to complete one orbit? This is a special case of Kepler's third law. (Hint: the speed is equal to the distance (circumference of the circular orbit) divided by the time to complete one orbit) (c) From your answer in part (a), what is the KE of the satellite?
