Is it the top, bottom, or the side? Also, if possible, what's the weakest side?

I recently saw the NOVA special on string theory. It left me pondering for the better part of the day. The program stated that there is a concentration of effort in using the atom-smashers to produce gravitons, in an attempt to document an "escaping" graviton which would provide proof of the theory. My question is if gravitons are detectable in the first place, wouldn't it be easier to find naturally occurring gravitons passing into or even through our brane, instead of trying to manufacture them? It seems to me that black holes would be better named "graviton stars," since according to what I understand of string theory, a graviton would be the only thing able to "escape" from the singularity. A black hole is, after all, a stellar sized atom smasher, so theoretically wouldn't they be radiating loads of gravitons? Even if all the gravitons are forced to exit our brane, wouldn't there be similar phenomena in parallel universes that would dump gravitons into our brane? Curious.

Picture this....a car stuck in the mud and a tree some distance away but exactly parallel. A man wishes to pull the car out of the mud by tying a rope to the tree and to the car. (It forms a v with the man at the tip) It requires a force of 10,000N to free the car from the mud. The man is capable of applying a maximum force of 1000 N. The theta angle I am trying to find is between the rope connected to the car and the imaginary line between the car and the tree....if you put a line on top of the v I mentioned earlier making it an upside down triangle....then theta would be the angle on the left.....please I'm not looking for just an answer...I want to know how to do this...I have worked for hours and all my answere do not seem right....thanks

You are on roller blades on top of a large hill. Your potential energy is equal to 1000 joules. You weigh 60kg (588N). If you start skating down this hill, your potential energy will be converted to kinetic energy. At the bottom of the hill, your kinetic energy will be equal to your potential energy at the top.
What will be your speed at the bottom of the hill?

I really don't understand this. Please help.

I now have to do a mouse trap car project, and it occured to me that to really get the fastest, most accurate, or strongest mousetap car, it would be helpful to know the exact force that a mousetrap exerts. I realize different mousetraps have different forces, but does anyone know what the force of a mousetrap is, or where to find it, or how to find it?
