As Galileo Galileo was said to have discovered by dropping objects off the Leaning Tower of Pisa, free-falling objects, like a returning bullet, will all travel similarly faster and faster, under the acceleration of gravity (about 9.8 m/s2). Because of the counter-force due to air resistance, objects will stop accelerating, reaching a terminal velocity dependent on their aerodynamic properties. A bullet should reach a terminal velocity of about 200 mph.

How fast in miles per hour would an object fall after 3 seconds?
At the end of 3 seconds, a falling object is falling at 65.8 mph faster than when it was released, ignoring air resistance.
How many feet per second does a bullet have to travel to be supersonic?
The dry air speed of sound is about 1125 FPS, so anything over that is considered supersonic.
How many meters will a 2kg ball moves starting from rest fall freely in one second?
The mass is irrelevant. If the object is in free fall (that is, air resistance can be neglected), an object will fall 4.9 meters in one second.
What is the range on a 9 mm handgun?
There are a couple of different answers, depending on what you mean. In general, a handgun bullet can travel about a mile on average, if the gun is pointed up at an angle and fired into the air. Most handguns can easily be shot accurately at ranges of 50 yards or less, but many skilled handgun shooters can shoot accurately at 100 yards, and some can even shoot fairly accurately up to 200 yards.
How fast does a 75 gram package fall at 9 feet 3 inches?
The mass of the package has little to do with its speed when falling under the influence of gravity. If air resistance can be ignored, then, it starts falling at 0 feet per second and accelerates at 32 feet/sec2 to a speed of 24.331 ft/sec (approx).
Can a bullet shot in the air kill someone?
Yes
If an object in motion will stay in motion what causes a bullet shot into the air to fall?
An object in motion will stay in motion until acted on by another opposing force. So gravity causes a bullet to fall back to the ground, but wind and air resistance cause the bullet to not fall strait back from where it came, aka one barrel. ____________ The above is true, only if Newtons theories are correct. If Newtons Theories are incorrect, then the bullet performs in the manner The Creator of all things and happensings decreed that it will. [see discussion on this comment]
How long does it take for a bullet fired into the air to come down?
after a bullet is shot in the air it travels 4,000 ft in the air and takes 59 seconds to a minute to come down
If you shot a bullet in to the air could the bullet kill you on its way down?
Yes, it could, or it could kill someone else.
Why are bullet trains so fast?
A bullets trains goes fast because of the streamlines in the air.
What is small as a bug as fast as a bullet and as light as a feather?
Um... air?
How fast would a .50 cal bullet Travel if Shot in Space?
The bullet will travel as fast as it would on earth (possibly a little faster, due to the lack of air resistance in the barrel). Once it left the barrel, it would continue with the same speed until slowed by gravity, or it entered a planetary atmosphere- or hit something.
If you shot a bullet straight into the air and it fell to land on your head would you die?
Probably. The bullet would be travelling slower than when it left the gun (see related question) but it would still be travelling fast enough to cause injury. In areas of the world where guns are fired into the air in celebration injury from falling bullets is not uncommon.
Could a bullet shot straight in the air come down and kill someone?
Yes. It has happened before.
What causes a bullet To lose speed and fall to the ground?
Gravity and air resistance will both play a part. Air resistance is likely to reduce speed and gravity will cause the bullet to be pulled towards the ground.
If you fired a gun in a vacuum would the bullet travel further than if you shot it on earth?
Yes, because there will be no air resistance.
What is the effect of air resistance on the trajectory of a projectile?
Air resistance cause a bullet to slow up more than it would if the air did not affect it. (In fact, no air means no air resistance, and only gravity would affect the shot.) The effect of air is called drag, and it (the drag) results in the curve of the arc of the shot being greater. The denser the air, the more the air acts to slow the bullet. What about moving air? Like a crosswind? You'd expect a bit of breeze (or crosswind) to push a bullet in the direction that the breeze is going. But almost all modern bullets spin to give them increased stability and improve the accuracy of the shot. The rotation of the projectile, imparted by the lands or rifling in the barrel of the gun, causes the force of the crosswind to act 90 degrees later in the direction of rotation of the bullet. This results in what is called bullet rise or bullet drop. Links are provided below for more information.
