A block X slides along a horizontal frictionless surface towards a stationary block Y, as illustrated in Fig. 2.1. [Figure 2.1] There are no resistive forces acting on block X as it moves towards block Y. At time t = 0, block X has momentum 0.40 kg m s⁻¹. A short time later, the blocks collide and then separate. The variation with time t of the momentum of block Y is shown in Fig. 2.2. [Figure 2.2]
