the hardest pitch ever was 106 mph
I don't know exactly but I've watched the Little League World Series enough and they always refer to Little Leaguers pitching speed in relation to MLB and I believe that 70 mph Little League would be around 100 mph MLB A 70 mph little league pitch is equivalent to about a 111 mph MLB pitch. (This is calculated based on an average little league pitch at 57.5 mph and an average MLB pitch at 91 mph.)
Softball pitchers pitch from 43 feet, while baseball pitchers pitch from 60.5 feet. Therefore, A 65 mph softball pitch is equivalent to a 91 mph baseball pitch. Each reaction time is approx .45 seconds.

Getting proper throwing technique can give you a few more mph, but if you are throwing normally anything less than 90 mph, no way you're throwing 100 mph. That is, unless you grow physically. It's a combination of physiology and mechanics.

Yes, up to forty mph or more. Lions top out around 35 mph.
