High-speed motion pictures (3500 frames/second) of a jumping 260 g flea yielded the data to plot the flea's acceleration as a function of time as shown in the figure (Figure 1). (See "The Flying Leap of the Flea," by M. Rothschild et al. in the November 1973 Scientific American.) This flea was about 2 mm long and jumped at a nearly vertical takeoff angle. Use the measurements shown on the graph to answer the questions. Figure 1 of 1 150 100 alg 50 0. 0.5 1.0 1.5 Time (ms)
