They will also hit at the same time a rock dropped from the same height as the gun barrels. (All fired and dropped at the same moment)

The rock doesnt have any forward momentum to keep it airborne, so I do believe it would hit the ground before the bullets

Not at all....

First one...

It's one of those wierd aspects of physics, but it holds

The forward momentum of the bullets do not keep them airborne. They are falling as they move forward. What zorstorer is saying is correct, all will hit the ground at the same time...the bullets will be further down range when they hit but they will hit the same time as the rock.

I think this would work if the bullets didn't have any stabilizing spin on them, but an OK example.

Forward momentum is only relevent to counteracting gravity if the object is creating lift. Bullet is designed to keep air pressure balanced around the nose and sides (read no lift), otherwise they would not fly true to target.

Soo....lemme see if I have this right.....the rock and bullets all hit the ground at the same time, its just that the bullets are a half mile away? That doesnt make alot of sense, but I never took physics so what do I know?

zorstorer · « **Reply #36 on:** June 10, 2006, 01:18:34 AM »

Think of it this way....

there is only 1 force acting to pull them to the ground, gravity.

the bullet creates no lift on its own to counter gravity.

so unless the bullet can change the gravity acting on it, it hits at the same time as the rock dropped from the same height at the same moment.

I believe you guys, since I never took physics, just seems strange.

Then you arent talking about trajectory of a bullet. Your talking about dropping a rock off a cliff, not a barrel at 3000 fps.

What Bruno said. Then fire your guns and the bullets will punch holes in the target and you can then see where they land.

Also, if you set the target to, say, 800, shoot at it, then type .target 150, you can get a close look at your results. .Target 0 turns it off.

That would work, I just zoom in

I am too lazy?

What's with all the negativity ol timer?

Dont get mad at me because you forgot to include velocity, and thought a bullet simply fell to the ground after it left the muzzle.

Considering the amount of technical discussion in this thread, I find it funny that none of you answered Phtom's relatively straightforward questions.
