an athlete completes one round of circular track of radius R in 40 second what will be his displacement at end of 2minutes 20 second
2minutes 20 secinds=3.5 rounds
So the displacement will be 22r

displacement= ending position-starting position.
As I calculate, he is opposite his starting position, or 2R, in the direction opposite the starting point. In polar coordinates, the displacement is
