(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A space shuttle of 68000 kg is placed in orbit at an altitude of 1000 km from the surface of the Earth. What energy must we provide?

3. The attempt at a solution

I will need to provide energy in order to decrease the potential energy and an additional energy for the kinetic energy of the rotation.

[tex]\Delta E_p=-G\frac{Mm}{R+h} + G\frac{Mm}{R}[/tex]

[tex]E_c=\frac{1}{2}mv^2=\frac{1}{2}mGM/(R+h)[/tex]

So,

[tex]E=-G\frac{Mm}{R+h}+ G\frac{Mm}{R}+\frac{1}{2}mGM/(R+h)[/tex]

Am I right?
