Subject: Re: Speed of a volley ball serve...


Sounds like a good high school science fair project. I've not heard of
many that made good statistical studies of anything. You would need to
film several serves, vollys, spikes, etc. to get a good number for the
average ball speed. Do this for several sports then calculate the
typical energy of the ball in each situation. Have your mom make a
nice poster.

It won't win, of course. Judges prefer environmental projects (and
things that they can understand) over good science.
