Nasa launches a satellite into orbit at a height above the surface of the earth equal to the earth's mean radius. the mass of the satellite is 780 kg. (assume the earth's mass is 5.97 1024 kg and its radius is 6.38 106 m.) (a) how long, in hours, does it take the satellite to go around the earth once? h (b) what is the orbital speed, in m/s, of the satellite? m/s (c) how much gravitational force, in n, does the satellite experience? n
