Newton's Third Law: Force Exerted by a Wall on a Colliding Ball

C. The wall exerts a greater force on the 2 kg ball than on the 5 kg ball since the force from the wall on each ball is equal to the force that each ball exerts on the wall. This is because the force exerted by the ball on the wall is equal and opposite to the force exerted by the wall on the ball, according to Newton's Third Law of Motion. Therefore, since the force applied by the 2 kg ball is greater than that of the 5 kg ball, the force exerted by the wall on the 2 kg ball will also be greater. The distance each ball rolls before coming to rest is not relevant to the force exerted by the wall on the ball.
