Question

a large retail store wants to ensure that no car can crash through its glass doors. to prevent this, the store installed concrete poles outside the doors. how will the poles prevent cars from crashing into the store according to newtons third law? a. the force of the car will be canceled by a greater force from the concrete poles. b. the force of the car will be canceled by an equal force from the concrete poles. c. the force of the car will be canceled by a smaller force from the more massive concrete poles. d. the force of the car will be canceled by concrete poles which dont apply any force since they dont move.

Explanation:

Newton's Third Law states that for every action, there is an equal and opposite reaction. When the car hits the concrete poles, the poles will exert an equal - magnitude force back on the car, canceling out the car's force and preventing it from crashing through.

Answer:

B. The force of the car will be canceled by an equal force from the concrete poles.
