If I hold a tennis ball up high in my hand, about to drop it, what kind of energy is taking place?

BONUS for 700 total points (if correct, click for 500 points, then add 200 points next time someone answers a 200 point question): Suppose you are an astronaut making a space walk outside your space station and your jet pack runs out of fuel. How can you use your empty jet pack to get you back to the station?
(this question will be an extra credit "short answer" question on your final)
You can throw your jet pack in the opposite direction of the station. When you apply a force to the jet pack, it will apply an equal and opposite force to you, which will push you back to the station (Newton's 3rd law of motion)
