For an eccentricity of 0.92 and semi major axis length of 9500 km, determine the apogee velocity for a satellite in elliptical orbit. Take μ = 3.986 x 1014 m3/sec2.

Correct Answer: 1322.21 m/s
Apogee velocity ua = √(μ(1-e)/a(1+e)) ua = √(3.986 x 1014 x (0.08/1.92)/(9500 x 103)) = 1322.21 m/s.

At an instant of time, a satellite in an elliptical orbit is at a distance of 500 km from the surface of the earth. If the semi major axis of the orbit is 8500 km in length, determine the magnitude of the satellite velocity. Take μ = 3.986 x 1014 m3/sec2.
