'C'
Explanation
## Step 1This problem is about the law of conservation of momentum in physics. The law of conservation of momentum states that the total momentum of an isolated system remains constant if no external forces act on it. In this case, the Mack truck and the Volkswagen are the isolated system.## Step 2When the Mack truck and the Volkswagen collide head-on, they exert equal and opposite forces on each other according to Newton's third law of motion.## Step 3However, due to the difference in their masses, the impact will be different for each vehicle. The Mack truck, being the larger vehicle, will experience less acceleration than the Volkswagen.## Step 4This is because acceleration is inversely proportional to mass according to Newton's second law of motion. Therefore, the impact force is the same for both, but the effect of the impact will be different due to their different masses.
