The froghopper (Philaenus spumarius), the champion leaper of the insect world, has a mass of 12.3mg and leaves the ground (in the most energetic jumps) at 4.00m/s from a vertical start. The jump itself lasts a mere 1.00ms before the insect is clear of the ground. (a) find the force that the ground exerts on the froghopper during its jump. (b) express the force of (a) in terms of the frog hoppers weight.
