In the analysis you did, you assumed that the acceleration of your body was constant during the time you were pushing off the ground. Was it actually constant? Explain. If your answer is "yes," describe the change in acceleration as your feet leave the ground. If your answer is "no," is assuming a constant acceleration a reasonable approximation? Explain.
Homework Answers
The answer is no. The acceleration of your body was not constant during the time you were pushing off the ground.
Assuming a constant acceleration only works as a good approximation if there is a region of increasing acceleration to counteract the region of decreasing acceleration at the top of the graph.

Read and conduct a critical analysis of postings. For response, your critical analysis of your classmate’s posting should be written to include the following topics: Identify important information (facts, experiences, data and so on). Identify the main conclusions drawn. Analyze the key concepts to understand your classmate’s line of reasoning. Identify the underlying main assumption(s), of your classmate’s thinking. The focus for your critical analysis is not whether or not you agree with the post, but how well was their...
