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?
Is a rocket engine a turbine engine? An airplane is flying at a velocity of 180 km/s at an angle of 37 degrees to the ground. At what speed would a truck have to drive in order to stay directly under the airplane? How fast is the plane g ...
Supersonic tunnels generate winds faster than the speed of sound (768mph or 1,235.9 kph). 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 bigge...
It's all very impressive, but it can be hard to wrap your head around in the abstract, so let's do a little bit of napkin math to really bring it home. First, let's establish some terms. Hypersonic is, obviously, supersonic on steroids. But while "supersonic" has the clear cut ...
Staying in the Air The string on the windshield tells the pilot if the plane is yawing The wings on a glider have to produce enough lift to balance the weight of the glider. The faster the glider goes the more lift the wings make. If the glider flies fast enough the wings will pro...
Combustion occurs in the engine only at supersonic speeds because the air has to be flowing at a high rate to be compressed. Rather than using a rotating compressor, like a turbojet engine does, the forward velocity and aerodynamics compress the air into the engine. Hydrogen fuel is then in...
Sonic Boom While we're here on the topic of sound and motion, we can also understand sonic booms. Say the car was moving toward you at exactly the speed of sound — 700 mph or so. The car is blowing its horn. The sound waves generated by the horn cannot go any faster than the sp...
How fast is the Parker Solar Probe traveling? The Parker Solar Probe is traveling at 430,000 mph, making it the "fastest human-made object in history," Rayl said. MORE: Binary star system found near the Milky Way's black hole: An 'amazing' discovery, astrophysicists say ...
Sound waves travel at around 761.2 mph at sea level. That’s fast, but nowhere near the 186,000 miles per second at which light travels from your TV or computer monitor to your eyeballs. The distance between speakers and your ears, though very small, also in...
