Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Textbook Question

Chapter 5, Problem 6P

The average speed of a nitrogen molecule in air is about 6.70 × 10² m/s, and its mass is 4.68 × 10⁻²⁶ kg. (a) If it takes 3.00 × 10⁻¹⁵ s for a nitrogen molecule to hit a wall and rebound with the same speed but moving in the opposite direction, what is the average acceleration of the molecule during this time interval? (b) What average force does the molecule exert on the wall?
