    1. The problem statement, all variables and given/known data

    Using a development similar to Kepler's law of periods for planets orbiting the Sun, find the required altitude of geosynchronous satellites above the earth.

    2. Relevant equations


    3. The attempt at a solution

    I'm honestly not even sure where to start. The correct answer is supposed to be 3.59*10^7m above the surface.

    Well you know the period and you want to find the radius. Just rearrange the equation and plug the numbers in.
