AI Thread Summary
Cracking a whip faster than the speed of sound is theoretically possible, but the sound of the crack would not be heard if the whip is cracked while moving faster than sound. The perception of the sound depends on the direction of the movement relative to the whip's crack. Inside a plane, one could crack the whip and hear it, while outside, cracking it forward would not allow for hearing the sound. However, cracking it backward might still produce audible results. The discussion highlights the relationship between speed, sound, and the direction of movement.

Could you crack a whip while moving faster than the speed of sound?

Yes, but you wouldn't hear the crack !
 
Depends on if you crack it before your ears or after your ears (measured in the direction of movement) :smile:
 
If you were inside a plane, yes. If you were outside, forget about a forward crack(using your arm), though you might be able to do it backwards.
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
