The operation period of a near earth satellite is about 84 minutes. What are the angular velocity and linear velocity around the earth The radius of the earth is 6.4 * 10 ^ 6m

The operation period of a near earth satellite is about 84 minutes. What are the angular velocity and linear velocity around the earth The radius of the earth is 6.4 * 10 ^ 6m

The formula of centripetal force is f = (MV ^ 2) r and F = MRW ^ 2, and the formula of law of gravitation - F = g * m1m2 / (R * r) (g = 6.67 × 10 ^ - 11n &; m ^ 2 / kg ^ 2), so g * m1m2 / (R * r) = (m1v ^ 2) r. after calculation, we can get the linear velocity around the earth (M1 is the mass of the satellite, M2 is the mass of the earth) g * m1m2
