Depends on how fast you throw it... ;)
It depends on how hard you throw it, obviously!
75 mph
To use a velocity ball, hold it in your hand and throw it with as much force as possible. The ball is designed to measure the speed of your throw. Make sure to take into account your technique and form when using the velocity ball to get an accurate reading of your throwing speed.
It will go as fast as it's terminal velocity
The shot put speed depends on the force behind the throw.
Simple flick the wii remote as fast as you can.
Avergae speed 40-60 mph- a few have had speeds in the 70s.
I am twelve and I can throw about 70-75 mph. For an average child maybe 80-85 mph.
There are innumerable URLs stating that his ball was measured with a radar gun at that speed in 1974, but I could not find any that explained exactly how accurate the measurement was. There's no question but that Ryan could throw a ball fast, but the question remains on exactly how fast.
It all depends on how fast that you throw the ball.
