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.
Moving at five times the speed of sound would be known as Mach 5, and is classed as Hypersonic.
Mark 5 (or hypersonic)
Mach 5.
YES
Aurora
Mach 5.
The magnitude of momentum is directly proportional to speed. A car moving at 100 km per hr has 5 times as much momentum as a car with equal mass moving at 20 km per hr has.
"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
Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.
Mach 5.
Mach 5, 5 times faster than the speed of sound!
Mach 5, 5 times faster than the speed of sound!
5 times the speed of sound
You break the sound barrier by moving at a speed that is faster than the speed that sound travels. In dry air, sound moves 768 mph which about 1 mile in 5 sec.
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)
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.
