Homework Help: physics

Posted by Kyle on Friday, September 17, 2010 at 9:57pm.

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?
