Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high-velocity cartridges such as the . 220 Swift and .
"The velocity (speed) of rifle bullets varies between 600 and 5000 feet (180 and 1500 meters) per second. Some bullets can hit targets as far away as 6000 yards (5000 meters)."
Ballistics. The standard AK-47 or AKM fires a 7.62 × 39 mm round with a muzzle velocity of 710 metres per second (2,329 ft/s). Muzzle energy is 1,990 joules (1,467 ft·lbf).
A bullet is fired at a typical muzzle velocity of around 2,700 ft. per second, or around 3,000 kilometres per hour.
U.S. Army Maj. Gen. Julian Hatcher's experiments in the 1940s found that a standard . 30 caliber bullet fired straight up could reach an altitude of 9,000 feet (2,743.2 meters) and return to Earth at a speed of 300 feet (91.4 meters) per second during its descent.
A 9mm Luger, according to Live Science, can fire bullets at approximately 1,360 mph, leaving them outrun by the top speeds of pacey jets like the United States' F-15E Strike Eagle (1,875 mph) and the Soviets' terrifying Mikoyan-Gurevich MiG-25, or Foxbat (capable of approximately 2,170 mph).
If you used regular high powered supersonic rounds in a weapon fitted with a Surpressor, you wouldn't hear the firing of the gun powder (depending how effective the Surpressor is) but you would hear the crack of the bullet breaking the sound barrier.
10 most powerful bullets in the world that redefined modern...
Despite their obvious advantages, the AK-47 and the AKM were considered by the Soviet military to have problems with accuracy, mainly because of recoil forces generated by the powerful 7.62-mm round and other forces known as blowback that were generated by the weapons' heavy internal mechanisms.
You probably already know that different calibers travel at different speeds. A rifle bullet's speed is the fastest in between (1200 - 4000 feet per second). Shotgun calibers come with the approximate speed of (1200 - 1600 feet per second) & the slowest calibers are handguns with a speed(of 950 - 1500 feet per second).
It would slow down on the way up as it gained altitude, then regain the same speed on its way back down. In reality, air resistance slows bullets pretty substantially, but bullets are smooth and dense, so it doesn't slow them down as much as it would need to to make them safe.
22 caliber bullet can travel around 1 mile to 1 1/2 miles. Some bullets, such as a 9mm, may travel up to three miles. Shot travels a shorter distance between 200 and 600 yards. The maximum distance that a bullet can travel is dependent upon many factors.
Speed of light—faster than a speeding bullet.
Unlike a car, which slows at a consistent rate when you take your foot off the gas, bullets slow down at a compounding rate. This means they lose speed slowly at first, then more rapidly as they continue to travel. This phenomenon has significant implications for body armor, which we'll explore in the next section.
Supersonic ammunition travels faster than the speed of sound, producing a distinctive “pop” known as a sonic boom. This noise, similar to thunder or fighter jets, is typical for most ammunition. Supersonic refers to speed, not sound, occurring when a bullet reaches or surpasses 1,125 feet per second.
Something like an AK-47, among the most common firearms in the world, doesn't fire bullets any faster than many other rifles, with a muzzle velocity of about 1,600 mph (2,580 km/hr). But because it's an automatic weapon, it fires continuously until the trigger is released, and can eject up to 600 rounds per minute.
If all else fails it can deploy flares and shaft to further disrupt missile guidance. So it's highly unlikely that a missile could bring it down. Moreover Air Force one is packed with advanced communication equipment including 87 telephones all integrated with a cutting edge long range communication system.
You Can't Curve a Bullet, Unless…
An object, bullet or otherwise, in motion must remain in motion. Of course, air resistance and gravity are outside forces which eventually bring the bullet to a stop if it doesn't hit its target before then. Finally, we know that every action has an equal and opposite reaction.
Because the shield limits the field of view, lifting and tilting the gun may make the sights more visible under these circumstances.
A bullet will accelerate until it leaves the barrel, typically around Mach 3. It will then immediately start decelerating at slightly more than 10 metres per second per second - gravity and air resistance will slow it down. At some point high in the air (work it out yourself) the bullet will stop and begin falling.
