Part a: The gure below shows a 0.30 kg baseball just before and just after it collides with a bat. Just before, the ball has velocity v1 of magnitude 12 mfs and angle 81 = 300. Just after, it is traveling directly upward with velocity v2 of magnitude 1D mls. The duration of the collision is 1 millisecond. i} What are the magnitude and direction of the impulse on the ball from the bat? ii] What are the magnitude and direction of the average force on the ball from the bat? Part b: The gure below shows graphs of force magnitude versus time for a golf ball being struck by a club along the x-direction. F F F 21;, 21*}, r, r : 6:0 3:0 12:0 (a) (b) (c) i} Rank the graphs (a)-(c) according to the magnitude of the impulse on the body, greatest rst. Explain your ranking ii} The golf ball initially starts at rest. Sketch the momentum p(t} vs. time graph in all three cases. In each case. indicate the nal momentum value in terms of Fe and to. 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 Solutlon: 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, andfor check the order of magnitude of an 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.
