A tortoise and hare start from rest and have a race. As the racebegins, both accelerate forward. The hare accelerates uniformly ata rate of 1.2 m/s2 for 4.4 seconds. It then continues ata constant speed for 11.8 seconds, before getting tired and slowingdown with constant acceleration coming to rest 81 meters from whereit started. The tortoise accelerates uniformly for the entiredistance, finally catching the hare just as the hare comes to astop.
