Horizontal distance travelled by a mobile experiencing a quadratic drag force: normalized distance and parametrization
Eur. J. Phys.
We investigate the problem of the horizontal distance travelled by a mobile experiencing a quadratic drag force. We show that by introducing a normalized distance, the problem can be greatly simplified. In order to parametrize this distance, we use the Pearson VII function, and we find that the optimal launch angle as a function of the initial velocity can also be fitted by this function.
