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?”

Question

Q2/ You want to move a 400-N crate across a level floor by pulling upward on the
rope at an angle of 30° above the horizontal. How hard must you pull to keep it
moving with an acceleration of a̟ = 0.5 m/s² ? Assume that µ, = 0.30.
