Proposed procedure assessing the strength values the coefficient frontal resistance of the projectile on the model the tangential acceleration it center mass. The necessary speed and acceleration is calculated by differentiating the functions obtained by interpolation from the center mass coordinate polynomials virtual coordinate systems. This allows the subsequent differentiation these functions to avoid the "loosening" effect, the discontinuity the derivatives polynomials in the docking points and increase the accuracy estimation the required quantity.
