32 ft/s²

Today the post-
woman brought
me the Arthur
Murray step-by-
step schematic of
the Beer Barrel
Polka. Except
there were no
steps shown, just
a dynamic topo-
graphical map 
of a hill with 
a figure rolling 
down it at an ever-
increasing speed,
something akin 
to 32 feet per sec-
ond per second.
