- Sure, *once it leaves the barrel.* But your frame of reference is too
- narrow -- you're ignoring the (upward) velocity the bullet had at the
- instant it left the barrel.

- I thought air resistance (i.e., drag) increased as the *cube* of velocity,
- not in direct proportion to it.
-
- On the other hand, I can see that the speed the bullet has when it leaves
- the barrel has some correlation with its potential for gaining altitude,
- and therefore its velocity on the way back down.

- Yeah, I got hung up for awhile on that picture of the dead guy whose dog
- got hungry and ate his nose and eyeballs. It had a remarkably therapeutic
- effect!
