What if you could experience flying in the same way it feels to ride a motorcycle or personal watercraft -- fast, fun and with the wind in your face? Go to the next page to find out how one company is aiming to make it happen. 2: Icon A5 Brady White as Santa Claus sits in the...
This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 kilometers). Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the ...
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. ...
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?
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...
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...

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...
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. The defining features of these and other recent Shinkansen trains are their extraordinarily long noses, designed not...
