How many feet per second does a bullet have to travel to be supersonic?
132 feet per second at 90 mph.
To answer this, we need to use unit analysis (a.k.a. dimensional analysis, Factor-Label Method, or the Unit Factor Method) to convert miles to feet and hours to seconds. Esse…ntially what we're doing is multiplying 62 miles/hour by a value equal to 1, like 60 seconds/1 minute (since 60 seconds and 1 minute express the same time period, the fraction is equal to 1) expressed in the right units to convert the expression to the units we want. 62 mi/hr * (5280 ft/1 mi) * (1 hr/60 min) * (1 min/60 sec)= (62*5280)/(60*60) ft/sec= 90.9333... ft/sec, or about 91 feet per second.
At 60 mph you are traveling at 88 feet per second.
85 Miles per Hour = 124.67 Feet per Second
55 mph = 80.66 feet per second
Light travels 186,282.397 miles per second. That is 983,571,056 feet per second.
125 mph = 183.33 feet per second.
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
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
At sea level in air sound travels approximately 1125 ft/s, however it changes depending on the material in which it travels. For instance, it travels faster in water.
88 feet per second.
at 60 mph your traveling 88 ft per second. at 65 you'd travel just over 88 feet per
75 mi/hr = 110 ft/sec
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
Depends on the rifle shooting it. The M16A2 rifle has a muzzle velocity of ~3100 feet per second. A rifle with a shorter barrel will have less velocity.
