What is the momentum of a bullet fired from a gun?

It is known as the Velocity (speed).


A bullet fired horizontally over level ground hits the ground in 0.5 seconds If it had been fired with twice the speed in the same direction it would have hit the ground when?

Assuming no affects from air and a smooth geography, both bullets would fall at the same rate of 9.81 m/s^2 toward earth, and hit the ground simultaneously. You have to look at the bullet's velocity as having a horizontal and vertical velocity vectors. The vertical velocity vector is independent from that of the horizontal. The horizontal vector would be the speed at which the bullet is fired, and the vertical vector is the speed at which the bullet falls due to gravity.


A 60 gram bullet is fired from a gun with 3150 joule of kinetic energy what is its velocity?

A 60 gram bullet fired from a gun with 3150 joules of kinetic energy has a velocity of 324.04 meters per second or 1,063.12 feet per second. (This is about 725mph).


Why projectile follow a curve path?

A projectile, launched by an initial force, such as exploding gunpowder in the barrel of a gun, travels in a straight line unless it is acted upon by another force. A projectile launched into the air from the earth's surface, is subject to the acceleration of gravity, which bends it's trajectory into a parabolic arc back to earth.


How much does a bullet slow down after being fired?

A bullet hardly slows down at all after being fired. While bullets come in a variety of shapes, sizes and weights, they are all failry aerodynamic and thus minimally impacted by the wind resistance (friction). A bullet's primary enemy is actually gravity. Once fired, it is a matter of time before gravity pulls the bullet crashing down into the earth...assuming it does not strike something first. While a high powered rifle will send a bullet farther and faster than a .38 pistol, fired from the same height, at the same trajectory over level ground, they will have almost identical hang times. Again, the faster bullet will simply go farther. The speed loss for any bullet, (buck shot not included) is negligible. It will strike the ground or object in its way with almost the same speed as when it was fired no matter how far away it is. This is of course excluding shots in the air where there is little horizontal movement and the trajectory is mostly verticle. Here, obvioulsy, gravity will take over and the bullet will ultimately fall back to the ground at the terminal velocity - much slower than muzzle velocity.

How does a bullet fired from a gun have ahigh momentum?

Momentum = mass x velocity A bullet has a high momentum because its velocity is really high.


Who many Fps for a 233 caliber bullet?

Bullets alone have no velocity. The .223 CARTRIDGE, when fired from an M16 rifle, will drive its bullet at about 3,200 fps. However, velocity depends on the makeup of the cartridge (powder charge, bullet weight) , and which firearm it is fired from.


If a bullet was fired down through the earth's atmosphere how long would it take and how fast would it be?

That would depend on the mass of the bullet, the bullet's velocity when it left the barrel of the gun, and from how high up the bullet was fired from.

How far does a bullet travel horizontally before gravity has an effect and takes over Is Newtons law correct that the bullet will hit the ground at the same time if it were simply dropped?

Gravity has an effect the instant the bullet leaves the barrel. The bullet starts to fall towards the earth at the same rate as the dropped bullet. However, (assuming the ground follows the curve of the earth, or you are shooting over water) the dropped bullet will hit the ground/water first. The reason is that the as the fired bullet falls the ground is receding away from it (the curve of the earth). The extreme example of this is: the bullet is fired fast enough that as it falls, the curve of the earth is 'falling' continuously away below it; we would say this bullet is now in orbit around the planet. However, if the ground you are shooting over is 'flat' (i.e. flat like a ruler, NOT following the curve of the earth) then: yes, the two bullets will hit the ground at the same time.


What is the velocity of 303 rifle bullet?

2441 feet per second when fired from the British SMLE rifle. Velocity will vary when fired from rifles with a longer or shorter barrel.


How fast is a bullet fired from a m16?

muzzle velocity is 3100 feet per second


If you shoot a gun up what is the velocity of the bullet coming down?

The velocity of a bullet coming down from altitude is the terminal velocity of the bullet fired. Since not all bullets are equal in mass, it would depend on the grain (weight) of the bullet fired, the caliber of the bullet, and the charge behind the bullet (which would determine the highest possible altitude it could reach). To determine the terminal velocity of any bullet, you must first know these variables and plug in those variables to the equation below: That is, * Vt = terminal velocity * m= mass of the bullet * g = gravitational acceleration * Cd = drag coefficient (wind resistance applied to the bullet as it falls) * ? = denisty of the medium through which the bullet is falling (the atmosphere) * A = projected area of the bullet (which can get complicated due to the shape of the ball). Essentially, the following is true: any bullet fired straight upward is not only potentially but very likely as deadly to anyone it might strike when it lands as if that same bullet were fired directly at that person.


Ammo fired down terminal velocity compared to ammo dropped at high altitude?

Fired ammunition from a firearm reaches a much higher initial velocity due to explosive propellant forces. In contrast, ammunition dropped from a high altitude reaches a terminal velocity where gravity pulling down is balanced by air resistance pushing up. The fired bullet maintains its higher velocity until slowed by air resistance and gravity, while dropped ammunition reaches a constant speed due to these opposing forces.


Does a bullet fired from a plane have more velocity than one fired on the ground?

Yes it does ! Even if both bullets are identical and fired from the same make of gun, the one in the plane will already have the velocity the plane is travelling at before it's fired.
