Orbits: Escape Velocity 
          Now consider the rocket/spacecraft
          after it has "escaped" the Earth, and traveled to the farthest reaches of
          space....
          (Note: We
          will assume the rocket/spacecraft has not lost any mass!)
          
          Q: What is the rockets Kinetic Energy
          so far from the Earth?
          Q: What is the
          rockets Potential Energy 
so "high" above the Earths surface?
          Q: What is the 
"final" total energy of the
          "system"?
