A small satellite of mass m is revolving around earth in a circular orbit of radius r_(0) with speed v_(0) . At certain point of its orbit, the direction of motion of satellite is suddenly changed by angle theta = cos^(-1) (3/5) by turning its velocity vector , such that speed remains constant. The satellite consequently goes to elliptical orbit around earth. the ratio of speed at perigee to speed at apogee is |
