gun trouble!!!?

Question

if i travel the speed that a bullet comes out of a gun and fire it. would the bullet double the speed or stay at the speed as me?

Answer 1

It depends on the direction you shoot it. If you fired it in the opposite direction to your motion as you zoomed by a stationary observer, he could literally watch the bullet drop straight down and land on the top of his foot without a fuss as if it slipped from his own hand.

Answer 2

If your travelling at v (the speed of a bullet after leaving a barrel) And shoot another bullet at v in the same direction then it would be faster than v, but not double. Remebering conservation of momentum you will realise that by shooting the bullet you will slow yourself down (ever fired a gun? it whacks you good and proper). If you somehow keep your speed fixed at v then the bullet would leave the gun at 2v, but you would observe it leaving at v.
Another thing to bear in mind is that air resistance will also slow the bullet down so eventually a plane may overtake its own bullet but by that time it is probably either part of a mangled crash, underneath the plane or has even just hit the floor.

Answer 3

I am understanding that you are travelling at a velocity v which is equal to the velocity of a bullet fired from a gun. Now if you fire the bullet, to a person stationery with respect to you, the bullet will appear travelling with 2v velocity while you are travelling at v. To you, the bullet will appear as if it is travelling at v.


This is true except when v = c, the velocity of light in vacuum.

Answer 4

At the speed of a bullet, we can safely say that the bullet doubles in speed for both you and observers at rest. (v<

Answer 5

speed of bullet Vb= Vy+Vb/(1+Vy*Vb/C^2)
where Vy= your speed, Vb=bullet speed and C=speed of light. If you and the bullet are travelling at speeds<

Answer 6

Well, if it didn't then a jet fighter would shoot itself down.
