La for\u00e7a militar\u00a0dels Estats\u00a0Units ha estat fent proves amb un nou vehicle hipers\u00f2nic terrestre que pot arribar\u00a0a la desorbitant<\/span>\u00a0velocitat de 10.620 km\/h. En aquest vehicle f\u00e0cilment es podria anar a Nova York en 35 minuts aproximadament, o fer la volta al\u00a0m\u00f3n\u00a0en menys de 4 hores.
\nEl nombre de\u00a0Mach<\/span><\/strong>, o simplement\u00a0Mach<\/span><\/strong>, \u00e9s el quocient entre la velocitat d’un objecte en un medi determinat i la velocitat del so en aquell mateix medi.
\nDepenent del resultat del quocient es pot\u00a0classificar per diferents velocitats:<\/p>\n

\u00b7<\/strong> Velocitat subs\u00f2nica: M < 0,7<\/p>\n

\u00b7<\/strong> Velocitat transs\u00f2nica: 0,7 < M < 1,2<\/p>\n

\u00b7<\/strong> Velocitat s\u00f2nica: M = 1<\/p>\n

<\/b>\u00b7 <\/strong>Velocitat supers\u00f2nica: 1,2 < M < 5<\/p>\n

\u00b7 <\/strong>Velocitat hipers\u00f2nica: M > 5<\/p>\n

El vehicle arriba al Mach\u00a08,2 que \u00e9s molt superior a la velocitat que poden arribar els avions de ca\u00e7a\u00a0actuals que solen estar entre el 2,8 i el 3,2.
\nEn el\u00a0v\u00eddeo\u00a0que hi ha no es pot veure b\u00e9 el vehicle per la seva gran velocitat, ni tan sols a\u00a0c\u00e0mera\u00a0lenta.<\/p>\n
