Final answer:
The magnitude of the force experienced by the car is greater than the magnitude of the force experienced by the truck due to the car's smaller mass.
Step-by-step explanation:
The magnitude of the force experienced by the car is greater than the magnitude of the force experienced by the truck.
According to Newton's third law of motion, every action has an equal and opposite reaction. When the car collides with the truck, they exert equal and opposite forces on each other.
However, the acceleration experienced by an object depends on its mass and the net force acting on it, as given by Newton's second law of motion (F = ma). The car has a smaller mass compared to the truck, so for the same force, the car will experience a greater acceleration. This means that the magnitude of the force experienced by the car is greater than the magnitude of the force experienced by the truck.
