A parachute is like a little nylon machine with all of the parts designed for light weight, durability and as few problems as possible during deployment. Considering the speed at which a skydiver is typically free falling -- about 120 mph (193 kph) -- and the lack of options if something...
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 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 ...
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...
When the airspeed reached about 17 mph (27 kph), I could feel the hang glider lift me off the ground. As I was lifted, I moved my hands from the sides of the control bar to either side of its base. To fly, I had to do two things: maintain a constant speed and keep my ...
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...
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...
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 ...
40 miles in 45 minutes is how fast in miles per hour? Convert 270 kph to mph Convert 600 meters to miles 1 mile in 18 minutes and 30 seconds is how fast in miles per hour? One hour = 3,600 seconds and 1 mile = 5,280 feet. Make a conjecture about how you could convert a ...
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...
