What is the speed of the fastest bullet in mph?
What is the speed of the fastest bullet in mph? These collective features mean that rifle bullets, such as that of a Remington 223, leave the muzzle at speeds of up to 2,727 mph (4,390 km/h) — fast enough to cover the distance of 11 football fields in a single second.
Is Mach 1 supersonic?
These speeds are referred to by Mach numbers. The Mach number is the ratio of the speed of the aircraft to the speed of sound. Flight that is faster than Mach 1 is supersonic. Supersonic includes speeds up to five times faster than the speed of sound, or Mach 5.
Is Mach 1 1000 mph?
So how fast is Mach One? The short answer is that it depends on where you are. But in general, it is a speed that exceeds about 1200 km/h or 750 mph.
Can 747 break Mach 1?
The Boeing 747–400 cannot top Mach 1, capped at 988 km/h, or Mach 0.8. The plane cannot exceed Mach 1, because its engines are not fast enough to propel the aircraft forward that fast. This also has to do with the plane's aerodynamics, because it is large and has dihedral wings.
