Hi, I am currently on the 3rd year of a 4 year physics degree, and I have a project for the semester entitled "The Physics of Projectiles". I am in need of suggestions for textbooks where I can get some good info on this topic. It is going to involve making things like catapults, crossbows, etc. and is going to take into account air resistance, which most textbooks don't seem to do when addressing projectile motion. So, if anyone can reccomend to me any good books of a suitable level for what I need, I would be very grateful. I was actually shown what looked like a good book on this topic, the title of which was "[Something] Structures", but I can't remember what the author's name was. If anyone knows what this book's full title and author's name is, I'd like to hear it. Thanks.
