Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially because of the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.
Amusement rides, sometimes called carnival rides, are mechanical devices or structures that move people to create fun and enjoyment. Rides are often perceived by many as being scary or more dangerous than they actually are. This could be due to the design, having acrophobia, or from hearing about accidents involving rides that are similar. [1]

It can be configured for non-lethal, less-lethal, and lethal effects. The system weighs 369 lb (167 kg) fully loaded with sensors, weapons, and ammunition. Its battery can last 3–12 hours, with a sleep mode to last for up to one week. The MAARS can move at 7 mph (11.27 km/h) and travel 800–1000 meters from its controller.

Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour.It is used in the United Kingdom, the United States, and a number of smaller countries, most of which are UK or US territories, or have close historical ties with the UK or US.
The following is a list of speed records for various types of vehicles.This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category.
