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.
The bullet slows down when firing upward and then coming down due to gravity, which acts as a decelerating force on the projectile. As the bullet reaches its highest point in the trajectory, gravity starts to pull it back toward the ground, opposing its initial velocity and causing it to lose speed. Additionally, air resistance can also contribute to the bullet slowing down as it descends through the atmosphere.
Yes, a bullet shot into the air can come down with enough force to cause serious injury or death. This is known as a "falling bullet" or "stray bullet" phenomenon, and it is important to never shoot a firearm into the air as the bullet can still retain lethal velocity when descending.
The speed of a bullet coming down, when fired vertically upwards and then falling back under the influence of gravity, will be the same as its speed when it was initially fired upwards. This is because gravity affects both the upward and downward trajectories equally, assuming no other forces are involved. The speed will depend on the initial velocity of the bullet when fired.
a machine gun can shoot 100 bullet drum in about 5-15 seconds it can shoot a target down in 3-5 seconds and it shoot at 120 mph
up then down.
The Mythbusters have tested this, and it may have lethal force coming down. However, even machine precision could not duplicate the one in a million shot of it actually hitting you when it comes down.
I assume what you are asking is "if you shoot a gun straight up in the air will the bullet come down at the point where it was shot from". The answer to that question is NO, the rotation of the earth will move the point of impact.
That depends on so many factors it would be hard to list, bullet type, angle, high velocity, etc etc. The important to understand about a 22 is they can travel a mile or more. Most people consider the 22 the least dangerous to shoot (for unintentional accidents) and they can easily be the worst. You MUST shoot them down or have a sufficient backstop.
When the powder is ignited, it starts a chemical reaction which creates gases. As these gases expand, the pressure separates the bullet from the casing, and propels the bullet down the barrel.
It goes up and eventually comes back down.
Get closer to it or hold it down.
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.
