This flea was about 2 mm long and jumped at a nearly vertical takeoff angle. Use the graph to answer the questions. (a) Is the acceleration of the flea ever zero? If so, when? Justify your answer. (b) Find the maximum height the flea reached in the first 2.5 ms. (c) Find the fleas acceleration at 0.5 ms, 1.0 ms, and 1.5 ms. (d) Find the fleas height at 0.5 ms, 1.0 ms, and 1.5 ms.
