3. The satellite is moving in an elliptical orbit around the earth with an eccentricity e = 0.25.
At the perigee, it is at a distance of 3.5x10 6 m from the surface of the earth.
a. Determine the radial distances in m from the center of the earth to the perigee and
apogee of the orbit.
b. Determine its speed in m/s when it is at its maximum distance (apogee) and minimum
distance (perigee) from the earth.
