Hypersonic tunnels create scary-fast wind blasts of 3,800mph to 11,400mph (6,115.5 kph to 18,346.5 kph) -- or even faster. Read More Wicked Wind Tunnels General Motors owns the world's biggest wind tunnel dedicated to auto testing. The fan has a 43-foot (13-meter) diameter. ...
Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach. Sound has a speed of Mach 1 and anything Mach 5 or above is considered hypersonic. While the speed of sound changes depending on temperature and altitude, Mach 5 is about 3,800 miles (6,116 ...

ALFA-X:The next generation of bullet trains, known as ALFA-X, is currently being tested at speeds of almost 250 mph (400 kph), although the service maximum will be "only" 225 mph. JR EAST Fast train:Japan's distinctive Shinkansen "bullet trains" have been plying the country's high-spe...
Hypersonic speed is five times the speed of sound. Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach. Sound has a speed of Mach 1 and anything Mach 5 or above is considered hypersonic. While the speed of sound changes depending on temperature and...
How fast (in meters/second) is an object moving on the earth if its speed is specified as Mach 0.6? How fast is 65 mph in meters per second? How fast is an object traveling after 3 s if its terminal velocity is about 35 m/s?
An absolutely critical component in today’s ADAS testing is highly accurate GNSS/GPS positioning systems. These systems are used to measure relative positions and velocity among vehicles and objects very accurately and with fast update rates. A vehicle configured with DS-VGPS GNSS system and DEWE...
