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 ...
Uncrewed torpedo speed claims range from 60 knots (110 km/h; 69 mph) for the British Spearfish torpedo [64] to 200 knots (370 km/h; 230 mph) for the Russian VA-111 Shkval. [ 65 ] ^ a b Ground effect vehicles (a.k.a. "Wing-In-Ground effect vehicles") are classified as maritime vessels, rather than aircraft, by the International Maritime ...
Another factor influencing rate of fire is the supply of ammunition. 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 ...
Bullets used in many cartridges are fired at muzzle velocities faster than the speed of sound [10] [11] —about 343 metres per second (1,130 ft/s) in dry air at 20 °C (68 °F)—and thus can travel substantial distances to their targets before any nearby observers hear the sound of the shots.

The 6 DoF modeling estimates bullet stability ((S d) and (S g)) that gravitates to over-stabilization for ranges over 2,400 m (2,625 yd) for this bullet. At 2,400 m (2,625 yd) the total drop predictions deviate 47.5 cm (19.7 in) or 0.20 mil (0.68 moa ) at 50° latitude and up to 2,700 m (2,953 yd) the total drop predictions are within 0.30 mil ...
The oldest evidence of stone-tipped projectiles, which may or may not have been propelled by a bow (c.f. atlatl), dating to c. 280,000 years ago, were found in Ethiopia, present day East Africa. [1] The oldest evidence of the use of bows to shoot arrows dates to about 10,000 years ago; it is based on pinewood arrows found in the Ahrensburg ...
