Question

an athlete completes one round of a circular track of diameter 200 m in 40 seconds what will be the distance covered and the displacement at the end of 2 minute 20 seconds?​

Answer 1

Answer:



Explanation:

Now, it is given that the time taken to complete one round of the circular track by the athlete = 40s. Thus, the speed of the athlete =200π40=5π m/s. Therefore, in 2 min 20s or 140s, the distance travelled by the athlete will be =5π×140=700π m.
