About Metres per Second

The metre per second (m/s) is the SI unit of speed. Brisk walking ~1.4 m/s; Usain Bolt's peak sprint ~12.4 m/s; speed of sound in air at 20°C 343.2 m/s; in water 1,481 m/s. Rifle muzzle velocities 370-1,200 m/s. Speed of light = exactly 299,792,458 m/s (the defined constant from which the metre is derived since 1983). 1 m/s = 3.6 km/h = 2.23694 mph = 1.94384 kn.

About Mach 20

Mach 20 ≈ 6,805.8 m/s (24,501 km/h) at ISA sea level - the peak heating regime of ballistic re-entry. Shock layer temperature exceeds 10,000 K; plasma sheath causes radio blackout. Space Shuttle decelerated through Mach 20 at ~75-80 km altitude; Apollo CM hit the atmosphere at ~Mach 36; ICBM warheads re-enter at Mach 18-24. DARPA HTV-2 reached Mach 20 in 2011. 1 Mach 20 = 6,805.8 m/s.
