Sažetak
This paper somewhat humorously shows a physical model of the semi-fantastic idea of an underground tunnel that would connect the two cities, which would be traveled through by the so called gravity train. The idea has existed since Robert Hook first presented it to Sir Isaac Newton. This problem is described by the system of ordinary differential equations. The solution of equation system is obtained numerically using Mathcad applications (with units) and function Odesolve.
