A froghopper is a 0.5 cm-long insect which has a mass of about 12 mg. A typical froghopper can jump straight up into the air to a height of 70 cm, an impressive feat for such a small insect. The "pushing off" phase of the jump lasts about 1 ms before the froghopper clears the ground and free fall motion begins. A. Draw a free body diagram and a motion diagram for the froghopper while it is in the air. B. At what speed will the froghopper need to leave the ground to reach 70 cm? C. Draw a free body diagram and a motion diagram for the froghopper during the “pushing-off" phase of its motion, while it is still on the ground but moving upwards. D. What is the acceleration of the froghopper during the pushing-off phase of its motion? E. What is the net force on the froghopper during the pushing-off phase of its motion? How does this compare to its weight?
