would it go into space or could it come straight back down and hit you or land beside you

No. Many stronger high powered rifle can fire a bullet at perhaps 3,000 feet per second as measured at the end of barrel. If that bullet were fired straight up, the bullet would be acted upon by both the force of gravity and friction. Ignoring friction: gravity will slow the bullet to the point where it is falling back towards you in under 14 seconds (rate of decrease = 32feet/second^2). The maximum hight that it can achieve would be less then 27,500 feet (well short of space - and below the average commercial airliner while at crusing altitude). But, the bullet will get nowhere near that height. Friction is an enourmous factor, and although the specific impact depends on the mass of the bullet, its aerodynamics, the density of the atmosphere, and wind, etc., it will slow our bullet down, and drop it within a tenth of that height.
Then it would be dropping towards you...

There is no way to accelerate anything into space that way. (Jules Verne didn't know that.) Escape velocity from the surface is so high that any projectile would be vaporized by the air before it got very far.
It could hit you coming back down, but there would be little chance of it. Also, a bullet's speed when it hits the ground will be much less than its initial muzzle velocity. The straighter up you shoot it, the greater the difference in speed. If it hit you, it probably wouldn't kill you, but it would hurt and leave a mark. If it hit you in the head, you might have to go to the hospital.

No bullet fired from a generic gun could make it to area. get away speed on the Earth's floor is approximately 11 kilometers consistent with 2nd, and that's assuming there is not any drag from the air. What could take place is the bullet could circulate consistent with threat 2000 ft up (or consistent with threat somewhat extra for a effective gun), attain a height, and tumble backpedal. A tumbling bullet in many cases has a non-deadly terminal speed because it falls. notwithstanding, in case you hearth the bullet at forty 5-degree attitude, it is going to take care of a ballistic trajectory, and could proceed to be pointed forward. it is extra probable for a bullet falling for the duration of this thank you to hold a deadly speed.

not unless the gun was very powerful and could shoot a bullet for miles....highly unlikely!!! Even if you stood in the same exact spot the bullet wud not come back down on top of you as the wind will carry the bullet in another direction as the velocity if the bullet decreases.

Rifles and pistols cannot shoot a bullet fast enough to go into space - the bullets always return to earth. This is why firing guns into the air is discouraged - every year, someone dies from being struck by falling bullets that were fired in the air to celebrate something.

The bullet would not even clear the troposphere, gravity would pull it down. If there was no gravity then the bullet would fly out into space.

If the gun could shot the bullet at a speed of 17,500 mph .then the bullet would go into orbit.................... if the speed was greater than 25,000 mph the bullet would completely escape Earth's gravity and begin orbiting the Sun.

ur bullet shuld hve a constat velocity of 11.2Km/sec to over come earths pull.if u shoot up straight,air resistace acts on it and its path is deviated.if u needs to a point at a target u shuld angleit at a specific teta

What goes up must come down, it's chances of coming straight back down and hitting you are as good as you shooting straight up. It could happen but very slim chance.

it would'nt
as the atmosphere would exert a very high pressure on the bullet and slow down its speed...
the gravitational pull of earth would slow down its speed...
there is a vast strech of atmosphere i.e. thousands of kms, it would not be able to travel such a distance...
