Ok so I think I have heard this "Statment" now about 20 times and I think it is complete , This is it:
" If you take a gun and shoot it straight up in the air
It will come back to the ground, but moving twice
as fast, as the speed it came out of the gun"
I know this is complete But I just need someone to verify, just to make sure there isn't a whole explination to why it falls twice as fast as it went up.
My "Hypothesis" if you will is that when you shoot a gun up in the air, the bullet was forced by the expanding force of blackpowder, But once it reached the falling point, there was not another force push it back down other then gravity. Which means that the maximum fall speed is around 150 mph tops, which is 204.39 FPS nearly nothing a gun can even achieve since it is such a low speed.
