It has been claimed that an insect called the froghopper (Philaenus spumarius) is the best jumper in the animal kingdom. This insect can accelerate at 4,000 m/s2 over a distance of 2.0 mm as it straightens its specially designed "jumping legs." Assuming a uniform acceleration, answer the following.
(a) What is the velocity of the insect after it has accelerated through this short distance? (Enter the magnitude of the velocity.)
This is 4 m/s. Correct
(b) How long did it take to reach that velocity?
