The motion of jumping insects is of interest not only to biologists, but also to those who design robots. FIGURE 5-46 shows the speed-versus-time graph for two different takeoff jumps of a 19-mg green leafhopper, as determined from high-speed videos.
(a) What is the magnitude of the average net force acting on the leafhopper's body during jump 1?
(b) What is the ratio of the force found in part (a) to the leafhopper's weight?
(c) Is the average force during jump 2 greater than, less than, or equal to the average force during jump 1? Explain.
