Question
On average, froghopper insects have a mass of 11.3 mg and jump to a height of 423 mm. The takeoff velocity is achieved as the little critter extends its legs over a distance of approximately 2.00 mm. Assume that the +?-direction is upward, and assume a vertical jump with constant acceleration.
What is the froghopper's acceleration ?jump during the jump (the jump itself, not the time in the air)?
During the jump itself, how much time ? are the froghopper's feet in contact with the ground?
What force ? does the ground exert on the froghopper during the jump itself? Express your answer in millinewtons.

- To take off from the ground, an airplane must reach a sufficiently high speed. The velocity required for the takeoff, the takeoff velocity, depends on several factors, including the weight of the aircraft and the wind velocity. A plane accelerates from rest at a constant rate of 5.00 m/s2m/s2 along a runway that is 1800 mm long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time tTOtTO needed to take off?
