The problem of deformation of an elastic half-plane 
under the effect of a finite load of special form on its boundary 
is studied theoretically. Using Laplace and Fourier transformations 
the authors obtained a finite relation for the total force on the 
axis of symmetry of the half-plane that is used to study momentum 
loss in impact of a short elastic rod against a smooth absolutely 
rigid obstacle. With certain limitations on the dimensions of the 
rod the authors obtained an accurate analytical estimate of the momentum 
loss that is associated with conversion of part of the energy of the 
striker to the energy of its transverse oscillations.
