Question

3. A train has broken through the wall of a train station. During the collision, what can be said about the force exerted by the train on the wall?

a. The force exerted by the train on the wall was larger than the force the wall could exert on the train.
b. The wall cannot be said to "exert" a force; after all, it broke.
c. The force exerted by the train on the wall was the same in magnitude as the force exerted by the wall on the train.
d. The force exerted by the train on the wall was less than the force exerted by the wall on the train.

Answer 1

c. The force exerted by the train on the wall was the same in magnitude as the force exerted by the wall on the train.

Step-by-step explanation:

Newton's Third Law states that if a body exerts a force on another body, this body exerts a force of equal magnitude but in the opposite direction on the body that produces it. So, one body cannot exert a force on another without experiencing a force in itself.
