An object moving at least five times the speed of sound is moving at hypersonic speed. Hypersonic speed is a speed greater than Mach 5. Aircrafts that can attain this speed are the X-15 rocket planes and Shuttle orbiter.
"Hypersonic" is a slippery, rubber, inexact word meaning faster than around five times the speed of sound in the same medium, or, you might say, 'super supersonic'. If you define it, for a moment, as "exactly 5 times the speed of sound at sea level", then the speed of light is only 174,806 times that fast. Nothing is faster than the speed of light.
Supersonic No. The fastest ever flown was mach 3.1 by the SR-71 Blackbird
No. If it did, then we'd have to call it light, not sound. Actually, there's a little bitof a difference between the two speeds. Like light travels about 879 thousandtimes faster than sound does.
The speed of sound in air is 343 m/s at a temperature of 20°C. The speed of sound changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure). Mechanical vibrations that can be interpreted as sound are able to travel through all forms of matter: gases, liquids, solids, and plasmas. The matter that supports the sound is called the medium. Sound cannot travel through a vacuum. Look at the link: "The Speed of Sound in Air and the effective Temperature".
Mach 5, 5 times faster than the speed of sound!
Mach 5, 5 times faster than the speed of sound!
An object moving at least five times the speed of sound is moving at hypersonic speed. Hypersonic speed is a speed greater than Mach 5. Aircrafts that can attain this speed are the X-15 rocket planes and Shuttle orbiter.
5 times the speed of sound
Mach 5 equals 5 times the speed of sound. As the speed of sound is variable according to air density Mach 5 is also variable.
the speed of sound in air is 343 m/s X 10 = 3430 m/s or 5 520.04992 k/s
Answer A travel with a speed which is more then the speed of sound. Answer In aerodynamics, hypersonic speeds are speeds that are highly supersonic. The term has generally been assumed to refer to speeds of Mach 5 (5 times the speed of sound) and above.
The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.
mach 25(twenty five times speed of sound)
"Hypersonic" is a slippery, rubber, inexact word meaning faster than around five times the speed of sound in the same medium, or, you might say, 'super supersonic'. If you define it, for a moment, as "exactly 5 times the speed of sound at sea level", then the speed of light is only 174,806 times that fast. Nothing is faster than the speed of light.
The speediest plane I have ever witnessed was the Boeing X-51 WaveRider which can run at up to Mach 5, which is 5 times the speed of sound.
The threshold for supersonic speed is 761 mph in a temperature like 70 degrees. Supersonic speed is any speed greater than the speed of sound (mach 1) and a speed five times the speed of sound (mach 5?) is referred to as hypersonic speed.
