If I remember Mr. Science, correctly, the time / speed / distance thingy 
plots out as a bell curve where the apex is zero speed, zero 
acceleration.  If you draw a line parallel to the base through both legs 
of the curve, the speed is the same and the acceleration is exactly the 
opposite -- e.g. traveling at the same speed, but it is decelerating at 
the same rate on the way up that it is accelerating on the way down.

Then again, I have two liberal arts degrees and a non-science advanced 
degree, too ... no one needs to go "engineer" or "physicist" on us ...
