We study a continuous model which describes the action of a velocity dependent drag on an
oscillatory system. The solution of the resulting differential equation turns out to be
asymptotic to a function which is expressible by means of the gamma and the
hypergeometric functions. Among the applications, we consider that to the free oscillations
around the fixed point which are ruled by van der Pol's equation. A section is devoted to
computational procedures and simulations.
