If an athelet complete one round of a circular track of diameter 50 m in 30 sec..find the distance travel by athelet and the magnitude of the athelet at

the end of 30 sec...???


Distance = 25π metre
Displacement = 0

The time taken by the athlete to complete 1 round = 30s

So if he runs for 30s then he will complete 1 round and will be at the starting point

Therefore the distance will be the circumference of the circle (ie 25π metre)
and the displacement will be 0.
