Asked by Kyle
A hare is resting behind a rock, when he suddenly sees a tortoise cruising by at a constant 4.0m/s. The hare, literally at rest initially, decides he must catch up with the tortoise, to save face. So, he accelerates uniformly to 6.0m/s in 4.0 seconds. Once he reaches 6.0m/s, he continues on at constant velocity indefinitely.
a) How fast is the hare traveling 2.0 seconds after he sets off?

(a) The hare is traveling 12 m/s after seconds. Just multiply acceleration by time since there was a standing start.
