How fast is the punch of an average person?

I was wondering if it's possible to break the sound barrier by punching very fast. Is it possible? And what is the avg speed of a human's punch?|||One kinematic analysis of the mechanical properties of a boxing punch from a professional heavyweight estimated a peak force on impact of 0.4 ton delivered at a velocity of 8.9 meters/sec, which represents a blow to the head approaching 0.63 ton. The latter is equivalent to swinging a padded wooden mallet with a mass of 6 kg at 20 miles per hour. Force is transmitted to the skull (causing transient deformation), which can cause contact trauma or focal contusions in the cerebral hemispheres beneath the point of cranial impact.





Just to give you an idea 0.63 tons is equivalent to 1260lbs of impact force. And that's from a professional boxer.|||I don't think so. when you punch it's the same muscle of throwing a baseball, and even for tennis or baseball when a player throws as hard as possible its like ~100mph. sound is like 600mph or something, so no.|||It differs from person to person I dont think there ever could be an average lol but like you could do a survey and just observe how fast they swing a freakin punch aye!
