Gunther and Linda Herzig and Tobias Jarzina and Frank Klinker and Sabine Knipper and Franz-Georg Schurmann and Marvin Wollek}, journal={arXiv: Popular Physics}, year={2020} }

If you want to get accurate predictions for the motion of water and air propelled D.I.Y rockets, neglecting air resistance is not an option. But the theoretical analysis including air drag leads to a system of differential equations which can only be solved numerically. We propose an approximation which simply works by the estimate of a definite integral and which is even feasible for undergraduate physics courses. The results only slightly deviate from the reference data (received by the Runge…
