  We study the impact of a body against a rigid wall. The body consists of a
rigid block and a viscoelastic rod described by the fractional Zener model.
Translatory motion of a body is influenced by the dry friction, described by
the set-valued Coulomb friction law. The problem is treated analytically by the
use of the Laplace transform method and solutions are obtained in a convolution
form. These solutions are compared with the ones obtained by using the
numerical method.
