Part A: Box 2 is connected to Box 1 by a masslejs rope. As a result of this setup, Box 2 is accelerated from rest up a rough incline by Box 1 [see the figure below}: {1: How many dis nct forces are doing work on Box 2? In answering this question. choose from the options below, and explain your answer: 1} One 2} Two 3} Three 4} Four 5} Five Part B: A box is pulled a distance d across the floor by a force F which makes an angle 0 with the horizontal (see figure below). T Q: If the magnitude of the force were kept constant but the angle O were increased, the work done by the force would do the following: in answering this question, chose from the options below, and explain your answer 1) Decrease 2) Increase 3) Remain the same 4) Either increase or decrease, depending upon what the initial angle 0 was 5) Either increase or decrease, depending upon the magnitude of the force FPart C: A rope ls used to drag a heavy box across a rough floor [through a displacement to the right}. See figure below: Duel "7 I I [51.12 . r H T one: "7 " l1: Rank the amount of energy dissipated by friction in the three cases, from greatest to least, assuming the same tension on the box and displacement of the box in all. In answering this question, choose from the following options, and explain your answer 1} Caselbcase2)case 3 2} Case3=case2)case 1 3} Case2:case3>case 1 4} Case 1 :v case 3 > case 2 5} Case1=case2=case 3 End of Problem 1 NOTE: For the following problems, where the term Work-Energy Theorem is used, this term is equivalent to the following equation: W\". = BAKE WNEF= the net work done on the system AKE = the change in kinetic energy of the system 1. Getting Started State the important information and summarize the problem. If possible, include a diagram. Note any assumptions you're making. 2. Devise Plan Devise a plan of attack before diving into the solution. Break down the problem into smaller, manageable segments. Identify which physical relationships you can apply. 3. Execute Plan Carry out your plan, explaining each step. The argument should be easy to follow. Articulate your thought process at each step (including roadblocks). Any variables should be clearly defined, and your diagrams should be labeled. 4. Evaluate Solution Check each solution for reasonableness. There are many ways to justify your reasoning: check the symmetry of the solution, evaluate limiting or special cases, relate the solution to situations with known solutions, check units, use dimensional analysis, and/or check the order of magnitude of an answer. Note: If you got stuck in the
