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 ...
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 ...
The Bullet was officially revealed on 26 July 2016; hand-built production was due to start in Chichester in 2017, but Bristol cars was liquidated in 2020 with no cars produced. [2] However, there are at least 8 completed chassis with BMW V8 running gear clearly visible in an urban explorer's video [ 3 ] of the site before the liquidation ...
The muzzle energy of the .950 JDJ is comparable to the kinetic energy of a 2,800 pounds (1,300 kilograms) automobile traveling at 20 miles per hour (32 kilometres per hour). In a 110 lb (50 kg) rifle, this will develop well over 200 foot-pounds force (270 joules) of free recoil energy.

Each powertrain has two electric motors driving a 2-speed transmission, built by Hewland. 1st gear can be used up to 275 mph. [7] On September 19, 2016, the Buckeye Bullet 3 achieved a new world record with a speed of 341.4 mph (549.4 km/h), beating its own previous record of 308 mph (496 km/h). Roger Schroer was the driver for the record ...

At 50 rps (3,000 rpm), a five-second burst from an M134 Minigun would use approximately 6.3 kilograms (14 lb) of 7.62 mm ammunition; this alone would make it an impractical weapon for infantry who have to carry a reasonable supply of ammunition with them. For this and other reasons, weapons with such high rates of fire are typically only found ...
