Q3. Figure Q3 shows a 1000 kg car hits a 4000 kg lorry. The car and truck has an initial velocity of 30mscG and 10msG, respectively. Suppose both vehicles move together after the collision, determine: (a) the common velocity of both vehicles just after the collision. (b) the impact force on the car if; 1) the car has a good crumble zone (0.3 s impact time). (ii) the car has a weak crumble zone (0.1 s impact time). (c) Give a brief comment based on the forces obtained in the above cases.
