Answers must include a full solution process. Your final answer must include the correct final units and the correct significant figures. Please include labelled diagrams for each question. Question 1: A 120 kg piano is at the top of a ramp that makes an angle of 30° with the level ground. As the piano slides down the ramp it experiences a force of friction. The coefficient of kinetic friction is 0.10. a. Draw free body diagram that represents the forces acting on the piano. b. Determine the magnitude of the normal force acting on the piano. c. Determine the magnitude of the kinetic force of friction acting on the piano. d. Determine the acceleration of the piano along the axis parallel to the ramp (i.e. what is the acceleration down the ramp?).

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?”
