Box 2 is connected to Box 1 by a massless rope. As a result of this setup, Box 2 is accelerated from rest up a rough incline by Box 1 [see the figure below}: In Preparation forthe questions below: Assume that the mass of Box 1 is m1. the mass of Box 2 is m:. and that mom: Assume both boxes start at rest Assume that, as a result of being pulled by boat 1, box 2 slides up the rough incline a distance D (as it is accelerated from rest] Assume that the rough incline has a coefficient of kinetic friction pk 0]: Determine the signs of the Work done by each the following forces, on each of the boxes, as Box 2 is accelerated from rest up the rough incline by Box 1: Explain each answer Box 2: 1] Hope Tension: +, . 0 2] Kinetic Friction: +, , U 3] Normal Force: +, , 0 4] Gravity: 1-, -, D Box 1: 1} Rope Tension: +, ,0 2} Kinetic Friction: 1-, -, 3} Normal Force: -i-J , 0 a} Gravity: +, J C12: Determine the sign ofthe net work done on each of the boxes as Box 2 is accelerated up the rough incline by Box 1: Explain both your answers: Hint: The WorkEnergyTheorem may be helpful here Box 2: Net Work: +, , 0 Box 1: Net Work: +, , 0 Q2: Using the Work-Energy Theorem, solve for an expressiOn for v, the final speed of Box 2 after it has slid up the rough incline a distance D. Your expression will depend upon m1, m2, D, pk, and g AND B 03: Use Newton's Second Law and Kinematics to Solve for an expression for v, the final speed of box 2 after it has slid up the rough incline a distance D. Your expression will depend upon m1, m2, D, pk, and g AND B. Your expression in Q2 should match that in Q1. 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
