A derivation of the parametric and cartesian equations of the trajectory of a projectile experiencing an air resistance (drag) force proportional to its velocity. As the thumbnail suggests, the path is no longer parabolic and the optimal launch angle is no longer 45 degrees.

About me: I studied Physics at the University of Cambridge, then stayed on to get a PhD in Astronomy. During my PhD, I also spent four years teaching Physics undergraduates at the university. Now, I'm working as a private tutor, teaching Physics & Maths up to A Level standard.
