When it comes down, it may reach terminal velocity.
As mentioned, every second it will get faster by 9.8 metres per second. So after 2 seconds it's doing 19.6 m/sec, after 3 seconds it's doing 29.4 m/sec, and so on.
But due to Earth's atmosphere, it may reach the point where it can't get any faster because of the air resistance. I don't know how fast this is for a bullet, and if I did know, I don't know if the speed would be enough to hurt someone.
It will be nowhere near the speed of the bullet from the gun, but I still wouldn't want to be the test dummy.

Yes because it does have enough speed to break free of our gravitational pull of earth/atmosphere. Think of the space shuttle and how much fuel it burns to break free of the our atmosphere......it's WWII technology which is what can only be described as very outdated. The speed of the bullet leaving the gun and even weather will help determine how high it will travel, The shape of the bullet! (as soon as a bullet leaves a gun it will start to slow down because of drag from the AIR (FRICTION))... once it starts coming back down toward the ground it could reach terminal velocity(maximum speed possible falling to earth due to earthlike forces - gravity/air) which is calculated by using mass and drag.
So the answer would be yes, so dont try it... Not a very good idea!

The bullet will come back as it has nowhere near the kinetic energy to reach space. And if you fire the bullet upwards randomly the bullet will still be moving in its latteral trajectory and retain enough velocity to kill. If, however, the bullet is fired absolutely and perfectly straight up the bullet will slow down and stop moving completely. A bullet can reach about 2-3 miles. Then it turns back and begin to accelerate. But air resistance will stop the acceleration at a point and will kepp the bullet moving at a constant speed. This is called the terminal velocity and, as shown by the Mythbusters, the terminal velocity for a bullet is not enough to cause a lethal injury. You would get hurt, seriously if stuck in the eye, but you probably wouldn´t die.

Search for MythBusters results 4-19-2006.
2 things can happen
1. Shooting straight up in the air , when the bullet comes down it will only be going about 70mph. thus not really fatal
2. Shooting at an angle, the bullet keeps its speed and can be fatal when it lands.

If the bullet has been shot with a velocity less than 11Km/s, then the bullet will come down because it is the escape velocity of any object on earth, i.e., if any object is thrown upwards with this velocity, it will go out of the earth's atmosphere and move into the space. and if the speed is less than the escape velocity then it will come down n if it hits someone it will definitely hurt him and hurt him hard.....

Yes,It will come back unless it goes up so high as to be beyond the Gravitational Pull of Earth.
And when it comes down,it can hurt an Object,Animal or a person .

If you shoot it exactly vertically over your head , it will go up till the speed of the bullet that is gradually reducing due to the gravitational pull of the earth , will stop after reachig height where its speed equals the gravity .(As it travells up , its mass increases and the increase in mass will retard the speed and it will come to zero acceletration) .It will stop movig up and will start falling down due togravity and its speed will also accelerate as it cointinues to fall.if yu stand in the same spot from where yu shot thebullet , it will hit yoiu and injure you.as its mass increses with the increase in the speed of its fall ( (The mass increases with the increase inacceleration)

during shooting a bullet from the gun it has greatest velocity which hurts human as well as metals also &
while bullet shoot upward it works opposing gravitational force so that it can not travel much distance,when it comes down it comes with less speed compared to shoot with gun since it has low weight it can not comes with high speed which does damage any one

yes it will come back down becuz it can't maintain tis speed forever and the gravity of the earth will bring it back down hard.
this is the reason why u don't throw things off a building of ferris wheel. it will kill some1 if its dropped from high enough

Ok well of course it is going to come back. Of it is shot at exactly strgiht up it will go up and will come right back down at it's terminal voloicty and it will hurt but won't kill you. If it is not stright up then it will have side ways violicty and it could kill you.
