Considering the speed at which a skydiver is typically free falling -- about 120 mph (193 kph) -- and the lack of options if something goes wrong, a parachute rig needs to be incredibly reliable. There's a lot of popular interest in the fine art of parachute packing. It has all the...
The fuel load is 800 to 1,000 pounds (about 450 kg) of fuel at launch, or approximately 150 gallons (600 liters). The missile has a cruising speed of 550 mph (880 kph). Guidance Tomahawk cruise missile escorted by F-14 Photo courtesy U.S. Navy The hallmark of a cruise missile...
On June 1, 2008, Gegenschatz exited an aircraft at an altitude of 15,000 feet (4,500 meters) and flew 11 miles (17.6 kilometers) over waters off the coast of Ireland at an average speed of 155 mph (250 kph) [source: The Daily Telegraph]. Lots More Information Related Articles How...
A typical Perseid meteoroid (which is what they're called while in space) moves at 133,200 mph (214,365 kph) when it hitsEarth's atmosphere(and then it is called a meteor). Most of the Perseids are tiny, about the size of a sand grain. Almost none of the fragments hit the ground...
So if you were theoretically able to hitch a ride on the Parker Solar Probe and take it on a detour from its sun-focused mission to travel in a straight line from Earth to Mars, traveling at the speeds the probe reaches during its 22nd solar flyby 430,000 mph (692,000 kph), the ...
A hard-disk platter can spin underneath its head at speeds up to 3,000 inches per second (about 170 mph or 272 kph)! The information on a hard disk is stored in extremely small magnetic domains compared to a cassette tape's. The size of these domains is made possible by the precision...
Treadmills delivered in the United States are usually set to display your speed in miles per hour -- but factory errors are possible. Switching your treadmill from kph to mph is usually as simple as pushing a button; it's finding the right button that's the trick. ...

At 75 mph (120.7 kph), the tires are using 12 horsepower, and at 55 mph (88.513 kph) they use 8.8 horsepower. All of that power is turning into heat. Most of it goes into the tires, but some of it goes into the road (the road actually bends a little when the car drives over ...
The X-15 was the experimental grandchild of Chuck Yeager's X-1, which first broke the sound barrier at Mach 1.06 (702 mph, or 1,130 kph), and is ancestor to the space shuttle and modern space planes [source: Darling]. As for air-breathing, powered airplanes, Eldon W. Joersz set ...
