- Alas, another one of my idols has fallen. As soon as it leaves the barrel,
- the only external force acting on the bullet is gravity and air resistance.
- Neglecting the air resistance (ahich is roughly proportional to, and
- oppositely directed to the velocity), the speed will be the same when it
- returns to the same height as the barrel. Air-resistance will make it
- a little less, but not by much compared to the muzzle velocity. Hope you're
- feeling better tomorrow Geoff, although I imagine that you're busy reading
- through your AMOK catalog in your spare time.
