Question

mr. jenkins accidentally backed his car into a stationary light pole. the collision caused damage to his cars bumper, trunk, and tail light. what is one way the light pole could be designed to help reduce the damage?
a. modify the base of the pole so that the pole will break when hit with a certain force.
b. design the pole so that it can be placed much deeper into the ground to anchor it.
c. modify the base of the pole so that the pole will not move upon impact with a vehicle.
d. design the pole so that it is made out of a metal that is harder and of higher density.

Explanation:

When a pole breaks under a specific impact force, it absorbs and dissipates the collision energy instead of transferring all of it to the car, which reduces the damage to the vehicle. Options B, C, and D would make the pole more rigid or fixed, increasing the force transferred to the car and worsening damage.

Answer:

A. Modify the base of the pole so that the pole will break when hit with a certain force.
