Determine the average orbital speed of the satellite if its orbital altitude above the Earth is 1200 km and the orbital period is 105 minutes. The radius of the Earth is 6400 km.
Given:
h = 1200km
T = 105min = 6300s
R = 6400km
Decision:
Speed = 2 Pi (R + h) n = 2 * 3.14 (6400 + 1200) * 1/6300 = 7.57km / s = 7600m / s
Answer: 7600m / s
