Momentum Principle and Energy Principle Problem

You will need to use the Momentum Principle to do the first part of this problem, and the Energy Principle to do the second part.

A satellite of mass 4500 kg orbits the Earth in a circular orbit of radius of 9.2x10^6 meters http://www.webassign.net/images/multiply.gif[/IMG] 106[/COLOR] m (this is above the Earth's atmosphere).The mass of the Earth is 6.0 http://www.webassign.net/images/multiply.gif 1024 kg.

What is the speed of the satellite?

*v* = 1 m/s

What is the minimum amount of energy required to move the satellite from this orbit to a location very far away from the Earth?

energy = 2 J

Not really sure what to do here, I feel as though I need more information to work this. Help is much appreciated.
