An earth satellite is revolving in a circular orbit of radius a with velocity `upsilon_(0)`. A gun is the satellite and is aimed directly towards the earth. A bullet is fired from the gun with muzzle velocity `(upsilon_(0))/(2)`. Neglecting resistance offered by cossmic dust and recoil of gun, calculate maximum and minimum distance of bullet from the centre of earth during its subsequency motion.
