On average, froghopper insects have a mass of 12.3 mg and jump to a height of 428 mm. The takeoff velocity is achieved as the little critter flexes its leg over a distance of approximately 2.0 mm. Assume a vertical jump with constant acceleration. How long does the jump last (the jump itself, not the time in the air) and what is the froghopper's acceleration during that time?
