A 60672 g woman in an elevator is accelerating upward at a rate of 120:54 cm/s2. Convert all given quantities into SI units. Show conversion factors. Determine the normal force exerted on the woman's feet by the oor. (Use g = 9:8m=s2) Does the normal force remain the same if the elevator is accelerating downward with the same magnitude of acceleration?

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?”
