When a flea (m = 450 g) is jumping up, it extends its legs 0.5 mm and reaches a speed of 1 m/s in that time. Part A - How high can the flea jump? How high can this flea jump? Ignore air drag and use g = 10 m/s. 0.0005 m O 0.1 m 0.050 m O 0.025 m Submit Previous Answers Correct Part B - Resilin Before it jumps, the energy is actually stored in a stretched elastic polymer called resilin. Let's take a simplified view of flea geometry. We assume that the resilin is initially stretched by 0.5 mm and that it becomes completely relaxed as the flea straightens its legs. What is the spring constant of resilin? A Value Units Review ?
