A Material Point Collision with a Rough Surface

The phenomenon of a material point collision with a rough surface is investigated. The character of the impact as a function of the angle of the point fall and the friction coefficient and the reconstruction coefficient is obtained. In the frame of Newton model, the impact is investigated as a process. The relationships of different parameters (tangential and normal components of the point velocity and the impulses of the surface reactions) during the impact are obtained. These results may be used for students teach in the theory mechanics.
