Chapter 2, Problem 61AP

An insect called the froghopper (Philaenus spumarius) has been called the best juniper in the animal kingdom. This insect can accelerate at over 4.0 × 10³ m/s² during a displacement of 2.0 mm as it straightens its specially equipped “jumping legs.” (a) Assuming uniform acceleration, what is the insect's speed after it has accelerated through this short distance? (b) How long does it take to reach that speed? (c.) How high could the insect jump if air resistance could be ignored? Note that, the actual height obtained is about 0.70 m, so air resistance is important here.
