    A tortoise and hare start from rest and have a race. As the race begins, both accelerate forward. The hare accelerates uniformly at a rate of 1 m/s for 4.8 seconds. It then continues at a constant speed for 12.4 seconds, before getting tired and slowing down with constant acceleration coming to rest 77 meters from where it started. The tortoise accelerates uniformly for the entire distance, finally catching the hare just as the hare comes to a stop 4)...
