We study nonlinear dynamics of a small ball moving vertically in a gravitational field and colliding with a moving table. Displacement of the table is approximated in one period of its motion by four cubic polynomials (we shall refer to this model as MC). The Poincare map, mapping a state of the ball at an impact to a new state at the next impact, is used to investigate the ball dynamics. Results obtained for the model MC are used to elucidate dynamics of the standard model of bouncing ball with sinusoidal motion of the limiter (model MS). Bifurcation diagrams are computed for the models MC and MS. Then fixed points and their stability are determined for the MC model and compared with our earlier results for the model MS. Finally, the birth of the low-velocity 2-cycle is investigated analytically for the MC model.
