Two satellites A and B are revolving around the earth circular orbits of radius r_(1) and r_(2) respectively with r_(1) lt r_(2) . Plane of motion of the two are same. At position 1, A is given an impulse in the direction of velocity by firing a rocket so that it follows an elliptical path to meet B at position 2 as shown. A?t position 2, A is given another impluse so that velocities of A and B at 2 become equal and the move together. For any elliptical path of the satellite of the time period of revolution is given by Kepler's planetary law as T^(2)alpha r^(3) where a is semi major axis of the ellipse which is (r_(1)+r_(2))/(2) in this case. Also angular mopmentum of any satellite revolving around the Earth will remain a constant about EArth's centre as force of gravity on the satellite which keeps it in elliptical path is along its position vector relative to the earth centre. If the two have same mass

The moon travels an elliptical path with Earth as one focus.The maximum distance from the moon to the earth is 405,500km and the minimum distance is 363,300km .What is the eccentricity of the orbit?
