Question

An athlete one round of a circular track of diameter of 2000m in 30s. Find the magnitude of the displacement of the athlete at the end of 30s

Answer 1

Since it is a circular track so after completing one round , the athlete will come back to the point from where he started. ......... Displace ment will be ZERO as displacement is the shortest path b/w two points and hence athlete has come back to the point so magnitude of Displacement = 0 at the end of 30 s.
