Caveat utilitor. Quoting from the source:

Suppose, further, that, in addition to the force of gravity, the projectile is subject to an air resistance force which acts in the opposite direction to its instantaneous direction of motion, and whose magnitude is directly proportional to its instantaneous speed. This is not a particularly accurate model of the drag force due to air resistance (the magnitude of the drag force is typically proportion to the square of the speed),

For a given launch speed, you can probably empirically find a value for "c" which is a good compromise. But if you change the launch speed significantly, that empirical value for c may no longer be a good approximation at the changed speed.

It would be interesting to compare the results of the above model to other models recently posted here on CD which implement drag proportional to speed squared.
