> Let me summarize the conflict in this example:
> The acceleration to be applied corresponds to 2x10^12 meter/(second squared) (in words: two times ten to twelve) which means in vacuum that water molecule may gain two times ten to twelve meter/second velocity at every second (e.g. for dilute case). And in the end, the velocities are:  2.6745 km/s or 0.2220 km/s. (in words: minus two point six seven four five kilometer/second and zero point two two two zero kilometer/second, respectively). Can you imagine a water molecule which goes with a velocity of two kilometer per second?

Easily :)
Are you familiar with molecular-kinetic theory ? Molecular speeds in 
range 0.5 - 1.5 km/s  are very common.
