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 1.2 m/s2 for 4.4 seconds. It then continues at a constant speed for 11.8 seconds, before getting tired and slowing down with constant acceleration coming to rest 81 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)

How fast is the hare going 3.1 seconds after it starts?   See solution

2)

How fast is the hare going 12.5 seconds after it starts?
See solution

3)

How far does the hare travel before it begins to slow down?

m

4)

What is the acceleration of the hare once it begins to slow down?

m/s2

5)

What is the total time the hare is moving?

s

6)

What is the acceleration of the tortoise?

m/s2

A hare and a tortoise compete in a race over a straight course 1.10 km long. The tortoise crawls at a speed of 0.160 m/s toward the finish line. The hare runs at a speed of 7.50 m/s toward the finish line for 0.880 km and then stops to tease the slow-moving tortoise as the tortoise eventually passes by. The hare waits for a while after the tortoise passes and then runs toward the finish line again at 7.50 m/s....

In a race between a turtoise and a hare, the hare stopped to eat a carrot for 12.5s while the turtoise walked at a constant speed of 2.00 cm/s toward the finish line. The hare then noticed the turtoise crosses the finish line and ran the same distance with constant acceleration in another 2.5s. 1) How far did the turtoise travel during his portion of the race? 2) what was the acceleration of the hare while he was running? 3)...

In a quarter-mile drag race, two cars start simultaneously from rest, and each accelerates at a constant rate until it either reaches its maximum speed or crosses the finish line. Car A has an acceleration of 10.9 m/s2 and a maximum speed of 109 m/s. Car B has an acceleration of 11.8 m/s2 and a maximum speed of 93.7 m/s. (a) Which car wins the race? (b) By how many seconds does this car win the race?

A tortoise can run with a speed of 0.13 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 5.0 minutes. The tortoise wins by a shell (20 cm). (a) How long does the race take? s (b) What is the length of the race?.

2020 COS-241: DATA STRUCTURES Problem 2: Simulation: The Tortoise and the Hare DESCRIPTION This project deals with the classic race between the tortoise and the hare. For this project, you be using random-number generation to move the creatures. To make things more interesting, the animals have to race up the side of a slippery mountain, which could cause them to lose ground. In this race either animal could win or there could be a tie with no clear winner. The...

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 4.7 m/s2 for 3.8 seconds. It then continues at a constant speed for 8.5 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 206.78 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...
