Homework Help: Geosychoronous Satellites and their KE/Orbitals

  1. Nov 8, 2012 #1
    1. The problem statement, all variables and given/known data

    Prove that the product of the kinetic energy and orbital radius of a geosynchronous satellite is constant.

    2. Relevant equations

    Not sure on the orbital radius part

    KE=KE = ½mGM/R

    3. The attempt at a solution

    I'm lost on where to begin. How exactly would I 'prove' it?

    What shape must an orbit have if it is geosynchronous?
