Generalized dynamical equations of plane curvilinear motion of a material body on a trench with account of a friction forces (their numerical analysis in some special cases)

In this paper we have derived the general dynamic equations of a plane curvilinear motion, taking into account the forces as a viscous as and dry friction. It’s founded a closed system of four nonlinear differential equations. Its analyzes of the solution in some special cases illustrated by the graphical in the view of different trajectories which charactering of the plane motion.
