For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
Example: A .44 Remington Magnum with a 240-grain (0.016 kg) jacketed bullet is fired at 1,180 feet per second (360 m/s) [2] at a 170-pound (77 kg) target. What velocity is imparted to the target (assume the bullet remains embedded in the target and thus practically loses all its velocity)?

The imperial unit kilograin foot per second (kgr⋅ft/s). "Grain foot per second" (gr·ft/s) can be obtained by measuring the mass in grains (gr) (7,000 to the pound) and velocity in feet per second (ft/s), but since their product yields a very large number it is common to multiply by a factor of 1 ⁄ 1000, obtaining the power factor in kilo ...
This is a list of laws concerning air guns by country.. Most countries have laws about air guns, but these vary widely. Often each jurisdiction has its own unique definition of an air gun; and regulations may vary for weapons of different bore, muzzle energy or velocity, or material of ammunition, with guns designed to fire metal pellets often more tightly controlled than airsoft weapons.
The propulsion system uses an obturating case base with a semi-combustible cartridge wall. It has a total weight of 41.1 lb (18.6 kg) and a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter, [2] which reaches a muzzle velocity of 1,670 meters per second (5,500 ft/s) using 8.1 kg (18 lb) of JA-2 propellant. Its maximum effective ...

Originally announced under the working title of "Project Pinnacle" in 2015, it was first shown to the public under camouflage at the 2016 Goodwood Festival of Speed. The Bullet commemorates Bristol's 70th anniversary, and is the company's first all-new car since the Bristol Fighter, which was produced between 2004 and 2011, as well as the first ...
