(a) Let's say you want to put a satellite 384,000 km away from Earth's center.  
Use Kepler's Third Law, and the reasoning used in Exercise 31 above, to compute 
the orbital period of such a satellite.  Express your answer in days.

(b) Compare your answer to Part (a) to the orbital period of the Moon around 
Earth.  If you did the problems correctly they should identical, within the margin 
of error of your calculations.  What does this mean to you?
