Find the energy necessary to put 5kg , initially at rest on Earth's surface, into geosynchronous orbit.
Do I use the formula U=GMm/r
G=6.67*10^-11
M=2.5*10^24
m=5
r=41000
Is this sort of right, any help would be greatly appreciated.

Dont you have to add the kinetic energy that the satellite will have in orbit?
Do i do this by k=1/2mv^2
If so what wll be my m and v then
