Answer:

The truck would be more damaging because it has greater mass than the car and truck is bigger than car. When two vehicles moving at the same rate of speed are involved in a collision, the vehicles weighs less will take the greater impact; the larger and heavier the vehicle, the greater the energy abd momentum.
