If you shoot a bullet up in the sky will it come down if it doesn't hit anything?

Question

If you shoot a bullet up in the sky will it come down if it doesn't hit anything?

Answer 1

The escape velocity to leave Earth is 11.2 km/s, so that would be one heck of a rifle.

Answer 2

What goes up must come down. (unless it has escape velocity).

Ergo, it will hit something.  If your lucky it will be a field or at worst somebody's roof.  If you aren't, it will be a kid.

Answer 3

yes of course !

even if it does not hit anything up, it has effect of gravity on it .

hence, it will 100% come down.

Answer 4

Of course it will.

Answer 5

yes it will due to a negative effect from gravitational force ,the bullet will be on air only for initial velocity / gravitational acceleration

Answer 6

Hi,

In actual it shall come back to the earth due to gravity, but if the velocity of the bullet is such that it over comes the gravitationla force of the earth, it will go out in space and never come back. I have forgotten the actual value of that velocity but I guess it was equal or more than 8 m/s. Note that same principal is applied in the satellites otherwise thay all had to fall in earth. Hope to answer you well. Keep smiling. Bye.

Answer 7

Yes. unless you hit santa.

How dare you kill Santa! You have destroyed the dreams of many children around the world.

I bet you killed the Easter bunny too--- mind you, we have enough bloody rabbits here.

Answer 8

yes, it will come down for sure.

Answer 9

Yes there have been many cases where a bullet has fallen from the sky and killed some1. The bullet reaches such a high speed that its almost as dangerous as it has been shooted.

Answer 10

It depends on the velocity of the bullet and at what angle it is shot into the sky. At an angle of 45 degrees to the horizontal, the escape velocity from the earth's surface is approximately 11.2 km/sec. This means that the bullet must have a velocity of up to this amount in order for it not to come back down if it doesn't hit anything. Frankly, I think this might be quite difficult since velocity is a product of mass and acceleration, and bullet mass is pretty small, so we must get a gun to shoot at a very very very...high acceleration or initial velocity for the bullet to make it out of the earth's atmosphere into space (if it doesn't hit anything)

Answer 11

Yes.

Answer 12

thats a really good question and im gonna star it but honestly i dont know

maybe u can search on google or yahoo

^_^

Answer 13

excluding air.  yes, one came through the roof of a building and into a container

Answer 14

yes

and sometimes when it hits things it still comes down

i remember when i was 9 i was at a summer camp and my leader was showing us how to shoot a bb gun and she **** it up and it hit the shelter ceiling and went right into her foot

bleck

Answer 15

Haven't You Ever Heard The Saying "What Goes Up Must Come Down?" That Applies To Everything But Gas Prices.

Answer 16

There is one twist here no one has addressed (as of this post)...sorry OverTheEdge...didn't see you at first.

The escape velocity of an object is approximately 11.2 Km/s.

No "ordinary" gun achieves this muzzle velocity and there is drag (air resistance), but it is not true that "What goes up MUST come down."

Answer 17

Eventually.
