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) what was the speed of the hare after running for 2.5s?

Solutions

Expert Solution

1)

The tortoise travelled a distance ,while the hare is stopped to eat a carrot.

In the next , the tortoise travels a distance

Total distance travelled by tortoise is

2)

Hare covers the same distance in time with acceleration starting from rest

Using equation

  

Acceleration of the hare is  

3) Using

Speed of the hare after running for   is

4) 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 1.1 m/s2 for 4.1 seconds. It then continues at a constant speed for 13.7 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....

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)...

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 the United States, males between the ages of 40 and 49 eat on average 103.1 g of fat every day with a standard deviation of 4.32 g. Assume that the amount of fat a person eats is normally distributed. Round the probabilities to four decimal places. It is possible with rounding for a probability to be 0.0000. a) State the random variable. rv X = the fat consumption of a randomly selected male in the US between the ages...
