I created another screen cast showing how to get started with a numerical calculation for one of my classes. In this case, the students are attempting to model the motion of an object falling with air resistance. The following example doesn't show the steps including the air resistance, but maybe it is enough to get someone started.
I did that in Excel and posted the results on the Mythbusters fan site. Their data on terminal velocity and the altitude needed to achieve it were incorrect, at least by my model. Considering how frequently they use those parameters (explosion stops guy falling out of airplane, bullet terminal velocity, others) I'd say it's certainly worth their while to consider.
Of course, they didn't.
