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 4, Problem 33E

You’re an engineer working on Ares I, NASA’s replacement for the space shuttles. Performance specs call for a first-stage rocket capable of accelerating a total mass of 630 Mg vertically from rest to 7200 km/h in 2.0 min. You’re asked to determine the required engine thrust (force) and the force exerted on a 75-kg astronaut during liftoff. What do you report?
