An artificial sattelite as a mars of 600 kg and moving towards moon.calculate its kinetic energy and potential energy in mJ relative to the earth when it is 50 km from launching and moving at 2500 km/h take acceleration of earth gravitational field as 790 cm/s*s

    KE=1/2 *600*v^2 convert 2500km/hr to m/s

    Now on PE, I am troubled by your graviational field. You list it as constant, however, if it is relative to earth, that field changes nearer Earth, by a significant factor, so PE relative to Earth is more than a constant field would indicate.
