In the spreadsheet I don't believe it makes any mention of the projectile shape though, and my project incorporates different styles of projectiles which probably have different drag coefficients. Thank you for your response though.

Actually the calculus teacher just suggested that I...
I need some help doing very basic mathematical analysis (what would be expected of a Calculus 1 and current Physics 1 student) for my project about tank projectiles, anything to calculate something about their air resistance/air drag, yet everything I have found has either been too simple (drag...
