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 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 is its incredible accuracy. A common statement made about the cruise missile is, "It can fly 1,000 miles and hit a ...
1 mile in 18 minutes and 30 seconds is how fast in miles per hour? How long will it take to go 1 mile at 248 mph? How do you convert km/million to cm/yr? How do you convert 43 hm to km? At 80 mph, how long does it take to travel 1 mile?
Forward bursts can be 20 meters (66 feet) wide and shoot out 100 meters (328 feet) at a speed of 100 mph (161 kph). These bursts leave a scorched region and lead to fire spread. The stronger the wind blows, the faster the fire spreads. The fire generates winds of its own that ...
The average skydiver plummets towards the surface of the Earth at a rate of 120 mph (193 kph) and can soar horizontally at 30 to 60 mph (48 to 97 kph). Typical wingsuit flyers fall at a rate of 50 to 60 mph (81 to 97 kph) and can jet through the air at 70 to 90 mph (11...
A train moves in a straight line at 30 mph for two hours. Then it goes at 70 mph for five hours. How far did it travel? What was the average velocity? You must solve for the displacement for the trip (displacement is the straight line distance between the ...
How did we get from this to bullet trains that reach up to 200 mph (320 kph)? duncan1890 / Getty Images Chugging across short distances or entire continents, trains act as a major form of transportation worldwide. Also called railroads or railways, trains carry within their cars...
Do all Falcons fly fast? Some are gliders, and some are flappers; some reach jetlike speeds, while others cruise by the clouds. The average bird travels a respectable 19 to 37 mph (30 to 60 kph), but the peregrine falcon flies atrates between 40 and 60 mph (64 and 97 kph)-- and...
As well as being able to alter the ride height, air setups allow for a variation of the spring rate. This is done via a series of chambers on each air spring, three in the case of the systemBentleyuses. In this three-chamber setup, two of the compartments can be either activated or...
Taking a suborbital approach, California-based aerospace firm XCOR is working on Lynx, a two-seat commercial aircraft designed for high-altitude, supersonic flight. If successful, Lynx will cruise at more than 2,500 mph (4,000 kph) to an altitude of 62 miles (100 kilometers), then descend...
