Supersonic refers to speeds greater than the speed of sound (Mach 1) but less than Mach 5. Hypersonic pertains to speeds from Mach 5 to Mach 25.
Speed measures the how fast an object is moving, which is determined by how much distance it travels over an amount of time. Its SI units are m/s (meters per second), however if you use other units in your calculations, the units can be different. A common example of speed me...
The speed of sound in air is 343 m/s. What is the speed of a supersonic plane that travels at 2.22 times the speed of sound? Give your answer in kilometers per hour and miles per hour. The world record for the hundred-meter dash is 9.77 s. W...

First, let's assume that it is possible — though it is not — for a human to move at the speed of light, which is 299,792,458 meters per second (983,571,056 feet per second), or about 186,000 miles per second. There's no issue, per se, with a person moving at a very fas...
Supersonic Speed in excess of that of sound. Velocity greater than the speed of sound. The SR-71 is characterized as a supersonic aircraft because it travels from three to four times the speed of sound. A supersonicaircraft can fly from New York to London in less than two hours. Genealo...
An object is 20 cm in front of a concave mirror, and the image is 5.0 cm in front of the mirror. What is the focal length of the mirror? What is the maximum speed during takeoff (above the height of point A)? What is the acceleration at the top of the ...
A fast radio burst is a bright and brief burst of electromagnetic radiation (light) seen in radio-wave frequencies. They usually last thousandths of a second. Some FRBs repeat, but the vast majority happen once and disappear forever.
What is a hypersonic weapon? A hypersonic weapon is a missile that travels at Mach 5 or higher, which is at least five times faster than the speed of sound. This means that a hypersonic weapon can travel about one mile per second. ...
