| Abstract |
We show that if the dependence of the drag force on the velocity is quadratic and the time dependence of the radius of a spherical body is linear, then the first integral of the equation of motion can be written out in closed form in terms of Bessel functions. To calculate the second integral, we propose concise approximate formulas. Their accuracy is verified by comparing the results obtained by analytic and numerical solution of the Cauchy problem. |
