2) Ray decides to paint the outside of his uncle's house. He uses a 4.0-m-long board supported by vertical cables at each end to paint the second floor. The board has a mass of 21 kg. Ray (70 kg) stands 1.0 m from the left cable. What are the forces that each cable exerts on the board? Ability A1: Can extract the information from representation correctly Needs Work Some of the information is extracted correctly, but not all of the information. For example, physical quantities are represented with numbers there are no units. Or directions are missing. Subscripts for physical quantities are either missing or inconsistent. Ability A5: Is able to construct a force diagram Inadequate Adequate All necessary information has been extracted correctly and written in a comprehensible way. Objects, systems, physical quantities, initial and final states, etc. are identified correctly and units are correct. Physical quantities have consistent subscripts. Adequate The diagram contains no errors and each force is labeled so that it is clearly understood what each force represents. Adequate Mathematical representation is represented symbolically (not just using numbers) and applies appropriate physics concepts to the situation. The mathematical representation is evaluated for its appropriateness and consistency. Needs Work FD contains no errors in vectors but lacks a key feature such as labels of forces with two subscripts or vectors are not drawn from single point, or components are drawn instead of forces. Inadequate Information that is extracted contains errors such as labeling quantities incorrectly, mixing up initial and final states, choosing a wrong system, etc. Physical quantities have no subscripts (when those are needed). FD is constructed but contains major errors such as incorrect mislabeled or not labeled force vectors, length of vectors, wrong direction, extra incorrect vectors are added, or vectors are missing. Ability A9: Is able to represent a situation with mathematics Needs Work Inadequate Mathematical representation is represented symbolically (not just using numbers) and applies appropriate physics concepts to the situation. No evaluation of the math in the problem is present. Mathematical representation lacks the symbolic part (the student plugged the numbers right away) has the wrong concepts being applied, or signs are incorrect. Missing No visible attempt is made to extract information from the problem text. Missing No representation is constructed. Missing No representation is constructed.

*PLEASE HELP WITH #3 and #4* You are in a class titled Introduction to Artistic Expression, and your final project must be completed in class. You know that you will be given one object and one board to work with to create a displays.  You also know that you must arrange the object on the board so it balances on a tiny pedestal.  Once completed, the display will be a single object resting on a board balanced on top of a pedestal. Draw a picture for the single mass model. Select a coordinate system.  Identify and label the quantities you can measure in this problem, such as masses and lengths. The unknown quantity in this problem is the locations of the mass in relation to the balance point.   On your picture, identify each force on your system.  Draw a free-body diagram of the board that includes distances from the balance point for each force. For now, identify an arbitrary balance point for the system. (This is OK, you will use the condition of equilibrium to make the correct choice…
