How many feet per second does a bullet have to travel to be supersonic?
Between 800 and over 4,000, depending on which bullet you had inmind.
1100 feet Update: You're just about right. Technically, though, it's a little over: 761 miles = 4018080 feet 1 hour = 3600 seconds ~1116 constitutes supersonic flight… at sea level
60 grains = 0.003888 kg\n3000 feet per second = 914.4 m/s\n. \n. \nKinetic Energy = 0.5 x Mass x Velocity^2\n. \nKE = 0.5 x 0.003888 x 914.4^2\n. \n= 1625.43158784 Joules
It depends on several factors, such as the specifications of the cartridge fired, and what type of gun is used to fire it (or more specifically, the barrel length). It can be …as little as about 300 FPS or as high as several thousand FPS.
A bullet travels 1500 feet per second how long to the nearest tenth of a second will it take to travel 2 miles?
7.04 seconds (5280 feet in a mile x 2 miles = 10560 feet) / 1500 feet per second = 7.04 seconds
1.46 feet per second at 1 mph.
15.543x10- 24 mph afterwards just figure out theterminal life and divide by the azimuth
At 60 mph you are traveling at 88 feet per second.
108.53 feet per second at 74 miles per hour.
75 mi/hr = 110 ft/sec
103 mph = 151.067 fps
Depends on the rifle shooting it. The M16A2 rifle has a muzzlevelocity of ~3100 feet per second. A rifle with a shorter barrelwill have less velocity.
To convert mph to feet per second, always multiply mph by 22/15. As an extension, to convert mph to feet per minute, always multiply mph by 88. To answer your question, (30) …x (22/15) = 44 feet per second
At 38 mph you are traveling at 55.73 feet per second.
