An athlete moves in a cucular path of radius r. He makes one second around the circular path in 40 seconds what is the displacement of athlete in one minute 20 seconds.
If athlete completes one round of a circular track of radius R in 40 seconds then after 2 m 20 sec =140 sec he would have completed 3.5 rounds that means he will be at the diametrically opposite point of starting point.

Answer:
If athlete completes one round of a circular track of radius R in 40 seconds then after 2 m 20 sec =140 sec he would have completed 3.5 rounds that means he will be at the diametrically opposite point of starting point.
Displacement =diameter=2R
