Jim,
It seems to me that, given the increased coefficient of restitution of the aluminum bat (over the wood bat) traveling in the opposite direction of the path of the ball, would actually slow the ball more than a wood bat would slow the ball (given equal force vectors).

I will concede the aluminum bat may well direct the path of the ball higher, but not faster, due to the trampoline effect of the hollow bat.

Of course, if the ball travels higher, the vertical component of its velocity will be greater when it comes back down.

Other than that, it seems like physics U.P. there work the same as everywhere else.
