Final answer:
In a rear-end impact in a forward collision, the damage is primarily produced by frontal deformation of the vehicle, which helps absorb the energy of the collision and reduce the chances of injury to the occupants.
Step-by-step explanation:
In a rear-end impact in a forward collision, the damage is primarily produced by a. Frontal deformation of the vehicle. When the front of one vehicle collides with the rear of another, the force from the impact causes the front of the struck vehicle to crumple and deform, absorbing the energy of the collision and reducing the chances of injury to the occupants. This deformation helps to increase the time over which the force acts, reducing the overall force experienced by the occupants.
