Ludwik seems readily amazed today - so let me do my little to help.
How about a retarding force formula *greater* than the bullet's weight.
Gee whizz! That means that a bullet fired straight down at mach 2
would DECELERATE!
I'd be willing to bet it would. Is that a surprising result? I'd be
shocked to find any real retarding force at one atmosphere pressure
that would *not* decelerate a bullet fired downward at mach 2.

where there's a component of downward velocity
for a speeding object in air, you see that there is an upwardly
directed component of drag - let's call it lift (?)
