Answer on Question #66038-Physics-Mechanics-Relativity A satellite going around Earth in an elliptic orbit has a speed of 10 km s-1 at the perigee which is at a distance of 227 km from the surface of the earth. Calculate the apogee distance and its speed at that point. Solution Perigee distance is ππ = β + π πΈπππ‘β = 227 + 6371 = 6598 ππ π£π = βπΊπ ( 2 1 β ) ππ π The semi-major axis of orbit is π= πΊπππ = 18724 ππ. 2πΊπ β ππ π£π2 Apogee distance is ππ = 2π β ππ = 30850 ππ. The apogee speed is π£π = βπΊπ ( 2 1 ππ β ) = 2.14 . ππ π π Answer provided by www.AssignmentExpert.com
