11,2 Km/s is the escape velocity from earth's gravity departing from the surface (obviously, the higher you go less velocity you need), so it's probably a rocket reaching out to outer space and not a ballistic missile meant to go down again, BUT there's a detail: this escape velocity is needed only if the body is a unpropulsioned projectile.

Space shuttles, ballistic missiles and rockets have propulsion, so they go up at a couple of thousands of km/hour
