This question is starting to drive me a little mad. First of all, the satellite can't be in a geosynchronous orbitANDtraveling at 5000m/s 325km above the earth. The two just don't jive.

Secondly, I am completely at a loss as to what formulas I should be using.

Should I simply be using 1/2mv^2 + mgh (where g = equals the reduced gravity of 8.8756069 at that height) for the question or is it much more involved than that?

I've read over articles involving critical velocities, gravitational attraction, circular motion, and centrifugal force until my head is spinning.

Can some please please give me a nudge in the right direction?

Thanks
