Two people stand on opposite ends of a long sled on frictionless ice. The sled is oriented in the east-west direction, and everything is initially at rest. The western person then throws a ball eastward toward the eastern person, who catches it. (1: Describe, from the options listed below, what happens to the sled as a result, and justify your answer. Options for Description of what happens to the sled: - the sled moves eastward and then ends up at rest - the sled moves eastward and then ends up moving westward - the sled moves westward and then ends up at rest - the sled moves westward, and then ends up moving eastward - the sled doesn't move at all 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 ofan answer. Note: If you got stuck in the Execute Plan stage and there is no solution to evaluate, you should still attempt to use estimation skills to get a feeling for what would constitute a reasonable answer to the problem.
