Fig. 3.1 depicts a collision at very low speed involving two cars moving along a straight road. Car B, with mass 800 kg, is travelling at $2.0\,\text{m s}^{-1}$ and hits car A, which has mass 1000 kg and is at rest. Following the collision, both cars continue in the same direction as car B was initially moving.
