It is the G-force which causes people to pass out. G-force is caused due to acceleration, not speed. A force of 5G can make a fit person pass out.
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
mach 1 = the speed of sound mach 2 is twice the speed of sound and that's how fast Concorde could travel, well, mach 2.3
The SR-71 is the fastest manned jet. Its fastest recored speed is Mach 3.3 (3.3 the speed of sound.)
Mach 3.2 which is 3.2 X the speed of sound
In August 2008, Sonic the Hedgehog was officially titled the fastest videogame character of all time with a top speed of light speed (using light dash). Average speed varies between speed of sound and mach 3. Tops Mach 5.4 running. Mach 10 for homing attack.
The Russian built Tu-144 is the fastest passenger aircraft with a maximum speed of Mach 2.35. (The maximum speed for the Concord is listed as Mach 2.2.)The Russian Tu-144 was retired due to technical and safety issues.Currently in service...The fastest private passenger aircraft in service right now is the Cessna Citation X business jet. It has a max speed of mach .92
Yes-but Mach speed determination is a function of altitude and speed. Rough calculations for the following aircraft all at the same altitude (50,000') to get a baseline comparison: 1. X-43A Scramjet 7,000 mph speed record. The fastest drone aircraft. Mach 10.5 2. X-15 4,520 mph world speed record. Fastest manned aircraft. Mach 6.8 3. SR-71 Blackbird 2,293 mph world speed record. The fastest jet aircraft in the world. Mach 3.4 4. MiG-25 Foxbat 2,115 mph. The fastest jet fighter in the world. Mach 3.2 F-15 Eagle 1,875 mph. Fastest United States jet fighter. Mach 2.8 Source: NASA & Aviation Trivia
It holds the world record for the fastest jet plane it can travel at Mach 3.3 (three times the speed of sound) 2,000 mph
There isn't really a maximum speed (except of course for the speed of light!) a human can survive. What would kill a human is the force generated by very fast acceleration (G force). I'm not sure of the maximum number of G's a human can withstand, but in a pressurized cockpit of say a fighter plane, a highly trained pilot might be able to get somewhere between 15-20 G's (15-20 times Earth's normal gravity), although once you get that high, the plane is going to have some trouble staying together as well.
Twice the speed of sound. Mach 2 :)
The Cessna Citation X (that is10) is reputed to be the fastest commercial aircraft - maximum speed is Mach .91
The speed of sound is a Mach. 1 Mach for a particular medium is the distance that sound would travel through that medium in 1 second.
