Here is a projectile with linear air resistance (the drag force is
proportional to the velocity magnitude). You can set the amount of
drag (g) and the other initial conditions.
The upper right graph shows the XY plot, while the lower two graphs
show the Vx and Vy velocities as a function of time. (Notice that as
time goes on, Vx -> 0, but Vy -> Vterminal.)
