- Homework Statement
- Two Earth satellites, A and B, each of mass m = 980 kg , are launched into circular orbits around the Earth's center. Satellite A orbits at an altitude of 4100 km , and satellite B orbits at an altitude of 12600 km .

Part A

What are the potential energies of the two satellites?

Part B

What are the kinetic energies of the two satellites?

Part C

How much work would it require to change the orbit of satellite A to match that of satellite B?

- Relevant Equations
- -G*M_e*m/r

r= km from center of earth which is the altitude + radius of earth

Change in U + Change in K=0

= -3.7298538168*10^13, -2.0594767123*10^13

Ive tried this equation with both masses and my homework keeps coming back with the wrong answer. I've tried checking my arithmetic but I cannot find anything wrong with it please help

haven't gotten the chance to try B but I am pretty sure it will be the same as A but positive is that right?
