Help with air resistance in projectile motion

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 not proportional to velocity squared) or way too complex (involving wind tunnel test data, which I don't think I'm collecting anytime soon). Any equations or online ballistic calculation software will do, one of my teachers suggested this spreadsheet ( , go to the bottom and click download the spreadsheet), which looked promising until I realized that the drag coefficient b was a pre-entered number. I don't have much numerical data about each projectile (here is an example ). Is there anything that any of you know of that can help me?
Thanks in advance for any assistance,
