Second Law Applications: synchronous satellite) A synchronous satellite goes around the earth once every 24 h, so that its position appears stationary with respect to a ground station The mass of the earth is m = 5.98 × 10 24 k g . e The mean radius of the earth is r = 6.37 × 10 6 m . The universal constant of gravitation is e 2 G = 6.67 × 10 11 N m k g 2 . Your goal is to find the radius of the orbit of a synchronous satellite that circles the earth. a) Describe what motion models this problem. Write down a vector description of the acceleration. Clearly indicate your choice of unit vectors and your reasoning for choosing them. b)
