Windows 7: A curious thing

A curious thing

This seems hard to believe. A high powered rifle can fire a bullet a very long way

One for the Mythbusters. In theory yes but I suspect there would be aerodynamic effects with real world bullets that would negate that.

if the bullet was fired at an angle, then it would be different.

if i remember my applied maths correctly, in theory the horizontally fired bullet (projectile) has been given no acceleration (by the gun) in the vertical axis, so the only force acting in the up/down plane is gravity, hence it behaves as if it was just dropped by the hand.

although in real life, the rifling of the gun would impart some spin on the bullet, so this may have a slight effect.

*edit* kado got there first!

Quite so. It is part of the BBC charter to "educate" after all.

So we don't need an actuator.

Just dropping a projectile on the bad guys head is sufficient.

A piano should do.

something that is perhaps easier to understand: same principle, but turned around a bit...

if the bullet was fired straight up, at a perfect 90 degrees, then in theory it wouldn't travel any horizontal distance, and should come back down on the gun.

this is presupposing that the bullet, the barrel, and the gunners are perfect. oh, and no birds getting in the way.

If you want to be technical about it, the bullet itself would come down exactly the same path, it would be you who had moved

I built my PC about 3 years ago. The Mother Board is a Gigabyte G41M-ES2L Socket 775. The CPU is an Intel Pentium Dual Core E2200 2.2Ghz 1MB 800Mhz Is there any reason with this combination that I can NOT run a 64 bit OS??
