one more time. This time the magnet has mass 6.38 kg and the force pulling it to the right is 68.4 N. When the magnet hits the floor, it continues being pulled to the right by the same magnetic force as before. The coefficient of kinetic friction between the magnet and the floor is 0.527. What will the magnet s acceleration be as it slides to the right along the floor? (Assume static friction is overcome and the magnet will slide.) 5.55 m/s^2 3.33 m/s^2 4.66 m/s^2 4.0 m/s^2

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?”
