HI all, I am new to the forum and have a real question for you physics buffs. It has to do with drag. For a mathematics paper, I am exploring the use of physics in accident reconstruction. I want to use calculus to create differential equations for the drag equation .5p(Cd)(A)v^2..... I want a drag equation that can be used for a car's motion. However, sources are scarce. I am having trouble with the integration and trying to get the equation into differential form. I am a BC calc student, but am new to physics and the application is a bit tricky for me. Help would be so very much needed!
