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?”

A woman in a lift is trying to weigh a parcel with a spring scale. The lift accelerates downwards at 1.7 m/s, then travels at a constant speed of 3 m/s, and finally decelerates at 1.1 m/s. During the first stage of the motion, the scale reads 6.6 kg. Note: a spring scale is a device for measuring weight, where the parcel is suspended below a spring that is attached to a dial. The extension of the spring is proportional to the weight of the parcel, but the dial is calibrated to give the mass of the parcel in kilograms. The dial will only give the correct mass if the parcel is subjected to the Earth's normal gravity. What does the scale read during the other stages of the motion? Second Stage kg. Third Stage kg. Give your answers correct to 1 decimal place.
