In the following problems, except where otherwise indicated, assume that the radius of the earth is 6378 km, the earth's mass is 5.976(1024) kg, the mass of the sun is 1.99(1030) kg, and the gravitational constant is G = 66.73(10−12)m3/(kg • s2).

The satellite is an elliptical orbit having an eccentricity of e = 0.15. If its velocity at perigee is vP = 15 Mm/h, determine its velocity at apogee A and the period of the satellite.
