Question 3. [25 points] A boy pulls a cart 19.8 m across a horizontal surface with a force of magnitude 17.3 N. The force is directed 25 degrees above horizontal and friction is negligible. The cart has a mass of 10 kg. A. [7 points] Sketch a free body diagram for the cart, labelling all the forces as we have done in class, to indicate the type of force and objects interacting. B. [6 points] What is the work done, in joules, on the cart, by the pulling force? C. [6 points] Determine the magnitude of all the remaining forces in your free body diagram. D. [6 points] If the boy now pulls with the same force in the horizontal direction, will the work done be greater than, less than or equal to the original work done (when the cart was pulled at an angle.) Explain how you know.
