By popular demand here is the thread on BC. It should be a good topic with so many professors here
So.......does weight (or mass) have anything to do with BC???
Here is my agrument, and I think it's pretty sound.
Take 2 bullets the same exact shape and size and external coating, but one is more dense (more mass/weight) than the other. They both leave the muzzle at the same velocity. To achieve this velocity the heavier bullet needs more force to propell it. F=M(A) Conversely, to slow the heavier bullet down requires more force, which means if they are traveling through the same density of atmosphere, the lighter bullet will slow down quicker than the heavier.
Can anyone refute this?
