Newton's Law of Gravitation states that two bodies with masses m1 and my attract each other with a force F, where r is the distance between the bodies and G is the gravitational constant. F = GMim2 72 Use Newton's Law of Gravitation to compute the work W required to launch a 1800 kg satellite vertically to an orbit 900 km high. You may assume that the earth's mass is 5.98x1024 kg and is concentrated at its center. Take the radius of the earth to be 6.37x106 m and G = 6.67x10-1i N.m2/kg2. (Round your answer to three significant digits.) W =
