haha, you kinda lost me... im real tired though, up all night last night :/ but back to the problem. Since said person is on a float, he is displacing his weight in water, but when he enters the water he is only displacing his volume in water. Since people are more dense than water, displacing weight is a larger amount, so when the guy takes a swim in the water, the water level will drop.

I never thought about it like that. Very good, now carry on.

you should read The Tao of Physics by Fritjof Capra.

um... If you were to hold a bullet and a gun the same distance above the ground. (assuming you are in a completely flat area) You shoot the loaded gun a the same time you drop the bullet. Which will hit the ground first? the fired bullet or the dropped one?

if you ignore air resistance and the curvature of the earth..
they would hit the ground at the exact same time.

i thought about specifically saying no air resistance... but would it really matter?i figure they both have the same resistance so it still takes them the same time to hit. but yeah curvature of the earth... blah

I was thinking that the air resistance on the pointed tip of a bullet would be different then air resistance on the bullet falling randomly.

Fuck all this stupid egghead shit. Lets get on to the physics of conception like the title says.

If you throw a baseball forwards off the front of a train it will be moving at the speed of the train + the speed of the throw.
A photon of light leaving that same train will always be moving at the exact same speed, regardless of the trains movement.
The speed of light in a vacuum is always the same no matter how the observer is moving relative to the photon. The only time the speed of light changes is when it passes through matter, this is the refraction of light that creates rainbows and the change of depth perception under water.

The resistance would be different, yes. But since the only resistance that matters is in the y direction, wouldn't it still not matter, assuming of course the dropped bullet does not face downwards.
