Optimal projectile launch angle in Python

I demonstrate using Python to solve a Physics problem where we want to find the optimal launch angle for a projectile to travel the furthest distance. We compare with & without Rayleigh drag force to see that drag has minimal impact on small objects traveling slowly over short distances. We also see that height changes our optimal launch angle.

Here is my source:

Look at the sections marked "change me". This is where you can experiment with different launch heights & with/without drag.
