About Centimetres per Second
A centimetre per second (cm/s) is 10⁻² m/s - the speed of slow animals, gentle breezes, and lab syringe pumps. Tortoises travel 0.5-1.5 cm/s; the fastest garden snail record is ~1.3 cm/s. A gentle breeze that barely moves leaves is Beaufort 1 ≈ 50-100 cm/s. Drug-delivery syringe pumps run 0.01-10 cm/s. Coarse silt settles in still water at ~0.2 cm/s (Stokes' law). Capacitive touch sensors detect finger motion at 1-10 cm/s. 1 cm/s = 0.01 m/s.
About Mach 5
Mach 5 ≈ 1,701.45 m/s (6,125 km/h) at ISA sea level - the conventional supersonic/hypersonic boundary. Above Mach 5, stagnation temperatures exceed 1,500°C, air dissociates around the vehicle, and ablative thermal protection becomes mandatory. Space Shuttle re-entered at Mach 25; Soyuz capsules at Mach 27; ICBM warheads at Mach 15-25. NASA X-43A scramjet reached Mach 9.6 (air-breathing record, 2004). 1 Mach 5 = 1,701.45 m/s.
