Final answer:
Front end header boards serve to block the forward movement of cargo and protect the driver from the cargo in case of a collision. They are related to the concept of impulse in physics, which is vital for safety in transportation. The correct option is c. Both of the above
Step-by-step explanation:
Front end header boards on a vehicle serve a critical safety function. They block the forward movement of cargo and also protect the driver from the cargo in the event of a collision. This relates to the concept of impulse in physics, which describes how a change in momentum can be spread out over time to reduce the force of impact. The use of plastics and crumple zones in modern cars is an example of increasing the time over which a collision occurs to reduce the forces experienced by the occupants.
When it comes to physics, an understanding of impulse is vital. This principle helps to save lives on the roads and in other situations. For example, when a person stands up from a seated position or when a car accelerates while driving, there is a change in momentum that can be analyzed using impulse. In both scenarios, there is an impulse experienced by the system, either the person or the car, respectively.
Therefore, the correct answer to the original question is 'c. Both of the above', as front end header boards both block the forward movement of cargo and protect the driver from the cargo in case of a collision.
