  We study a problem of description of macroscopic body motion in the frame of
nonrelativistic Snyder model. It is found that the motion of the center-of-mass
of a body is described by an effective parameter which depends on the
parameters of Snyder algebra for coordinates and momenta of particles forming
the body and their masses. We also show that there is reduction of the
effective parameter with respect to parameters of Snyder algebra for
coordinates and momenta of individual particles. As a result the problem of
extremely small result for the minimal length obtained on the basis of studies
of the Mercury motion in the Snyder space is solved. In addition we find that
relation of parameter of Snyder algebra with mass opens possibility to preserve
the property of independence of the kinetic energy on composition, to recover
the weak equivalence principle, to consider coordinates as kinematic variables,
to recover proportionality of momenta to mass and to consider Snyder algebra
for coordinates and momenta of the center-of-mass of a body defined in the
traditional way.
