A satellite moves in a circular orbit around Earth at a speed of 4705 m/s. (a) Determine the satellite\'s altitude above the surface of Earth. m (b) Determine the period of the satellite\'s orbit. h . Solution r = G M / v2 = (6.673 * 10-11 * 5.97 * 1024) / (47052) = 1.799 * 107 m The satellite\'s altitude above the Earth\'s surface is h = r - R = (1.799 * 107) - (6.378 * 106) = 1.16 * 107 m The satellite\'s orbital period T = 2 pi r /v = (2 pi * 1.799 * 107) / 4705 = 24024 sec = 6.67 hrs.
