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 1.4 m/s2 for 4.8 seconds. It then continues at a constant speed for 13.6 seconds, before getting tired and slowing down by constant acceleration coming to rest 131 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.
1. What is the acceleration of the tortoise?
2. What is the total time the hare is moving?
3. How fast is the hare going 1.4 seconds after it starts?
4. How fast is the hare going 7.8 seconds after it starts?
5. How far does the hare travel before it begins to slow down?
6. What is the acceleration of the hare once it begins to slow down?
