Mach 5

Mach 5 is a term used in space and astronautical engineering to refer to the speed of an object that is traveling at five times the speed of sound, or approximately 3,836 miles per hour (6,174 kilometers per hour) at sea level. Achieving Mach 5 requires advanced propulsion systems and materials that can withstand the extreme heat generated by air friction at such high speeds. Mach 5 technology has potential applications in hypersonic flight, space exploration, and military defense.
