If a small sports car collides with a massive truck, which vehicle experiences the greater impact force? Which vehicle experiences the greater acceleration? (Explain)

The forces between the truck and the car have the same magnitude and in opposite directions. This concept follows the the Newton's Third Law. Basically a force describes a particular type of interaction between two objects (parties). Since an interaction always involves two parties and therefore will result in two forces, in which case each object applies a force on the other object and receives a force of the same kind same magnitude but in opposite direction from the other object.

Although the forces are identical in magnitude, the object with smaller mass will experience a larger acceleration. That is why we see that the car will be bounced off a lot more than the truck does after the collision. It is the acceleration that we feel and that makes the speed and displacement.
