What is the minimum energy needed to launch a payload of mass m to an altitude that is

one Earth radius, RE $,$ above the surface of the Earth? $($Note$1$: that g is the gravitational

acceleration on the surface of the Earth and g $=$ GMe

R$2$

e

$.$ Note$2$: the described situation is just

trying to get the payload to the described altitude, and not put it in orbit around the earth

at that altitude.$)$
