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

9.2 106 m (this is above the Earth's atmosphere).The mass of the Earth is 6.0

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.
