Question

An athlete completes one round of circular track of diameter 200 in 40 sec. What will be the distance and displacement at the end of 2 min 20 sec.​

Answer 1

Answer:

500 distance in 2min 20sec

Answer 2

Answer:

hope it will help you..

Explanation:

Time taken= 2min20sec= 2*60sec+20sec= 140sec

Diameter=200m

radius= 200/2= 100 m

In 40 sec the athlete complete one round.

so, in 140 sec the athlete will complete= 140/40sec= 3.5 round

distance covered in 140sec= 2*22/7*3.5=2200m

At the end of his motion, the athlete will be in the diametrically opposite position.

displacement= 200m
