High-speed motion pictures (3500frames/second) of a jumping 280ìg flea yielded the data to plot the flea's acceleration as a function of time as shown in the figure (Figure 1). This flea was about 2 mm long and jumped at a nearly vertical takeoff angle. Find the initial net external force on the flea. How does it compare to the flea's weight? Find the maximum external net force on this jumping flea. When does this maximum force occur?
