3000 rpm and a 12.5" wheel does the trick, but of course this needs to be refined a lot. We probably don't need it to be 12.5" for starters.

just for general knowledge assuming close to complete transfer of speed to the ball you threw that ball about 50 meter/second well over the maximum.


If you you kept the same RPM and used a 3 inch wheel you would be right on the speed limit of 12 meters/second
