Two people, one of mass 100 kg and the other of mass 50 kg, stand facing each other on an ice-covered (essentially frictionless) pond. If the heavier person pushes on the lighter one with a force F, then A. the force felt by the heavier person is (-1/2)F B. the force felt by the person is -2F C. the magnitude of the acceleration of the lighter person will be half of the magnitude of the acceleration of the heavier person D. the magnitude of the acceleration of the lighter person will be twice the magnitude of the acceleration of the heavier personwww.crackap.com

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?”
