Here's the breakdown:

* Newton's Third Law: For every action, there is an equal and opposite reaction.

* In a collision: When a vehicle collides with an object, it exerts a force on the object. At the same time, the object exerts an equal and opposite force back on the vehicle.

* Rebound: The rebounding of the vehicle is a direct consequence of this equal and opposite force. The force exerted by the object pushes the vehicle back.

* Time: If the time of contact is the same in both situations (the vehicle hitting the object and the object hitting the vehicle), the forces are equal in magnitude and opposite in direction.

Important Note: While the forces are equal in magnitude, the effects on the vehicle and the object can be different due to their masses and the nature of the collision. For example, a heavy vehicle might barely budge a light object, but the force it experiences could still be significant.
