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?”

Using a torsion balance similar to the one used in the Cavendish Experiment, a group of scientists determined that the force of gravity between the small masses (q) and the large masses (Q) was 1.80 X 10 - 3 N when their separation distance (d) was 0.10 m. Suppose the separation distance (d) was then tripled to 0.30 m, what is the new force of gravity between q and Q? Explain your answer using words or proportionality equations.
Question 26 Out of curiosity, a physics student checks the mass of their favorite chocolate bar, the Newton bar, and compares it to its biggest rival, the Hooke bar. The student notes that both bars should have the same mass since the values stamped on the wrappers by the manufacturers are the same, which are both 80.0 0.2 g. Using a digital scale in one of the physics labs, the student weighed 10 chocolate bars for each brand, and averaged the results for both and recorded the results in their notebook as: the Newton bar: (79.6 ± 0.2) g the Hooke bar: (79.7 ± 0.1) g Which of the following statements best describes the comparison between the two different chocolate bars masses, as well as the stamped value? O There is not enough information given to compare the two chocolate bars with each other, or the stamped value.

A skydiver weighing 65 kg jumps out of a helicopter hovering at a height of 3 kilometers. Assume a cross-sectional area of 0.5 square meters. After thirty seconds of free fall, the skydiver deploys the parachute and the cross-sectional area becomes 40 square meters. Reproduce the model for the skydiver in Excel or VenSim. In VenSim you may have to make At quite small in order not to throw an error. Because you reach terminal velocity relatively quickly your answer should not be particularly sensitive to the value of At you choose. What is the skydiver's terminal velocity without the parachute? meters/second What is the skydiver's terminal velocity with the parachute? meters/second
