A satellite of mass m is in an elliptical orbit around the earth. The speed of the satellite at its nearest position is (6GM)/(5r) where r is the perigee (nearest point) distance from the centre of the earth. It is desired to transfer the satellite to the circular orbit of radius equal to its apogee (farthest point) distance from the centre of the earth. The change in orbital speed required for this purpose is

Imagine that you are in a spacecraft orbiting around the earth in a circle of radius 7000 km (from the centre of the earth). If you decrease the magnitude of mechanical energy of the spacecraft − earth system by 10% by firing the rockets, then what is the greatest height you can take your spacecraft above the surface of the earth? [Re = 6400 km]
