Gravitational potential and potential energy

A rocket of mass M is launched vertically from the surface of the earth with an initial speed V. Assuming the radius of the earth to be R and negligible air resistance, the maximum height attained by the rocket above the surface of the earth is



ΔK.E.=ΔU12MV2=GMeM1R1R+h   .......(i)

 Also g=GMeR2.........(ii)

On solving (i) and (ii)  h=R2gRV21
