Question

An athlete is running around the circular track of radius 100 meter. calculate the distance and displacement when he completes one round of circular track.

Answer 1

Answer:

given r = 100 m

to find displacement and distance

displacement is the shortest distance between starting point and end point. as he comes back to the same point from where he started from, his displacement is zero.

distance is equal to the circumference of the circular track => 2πr => 2*22/7*100

=> 628.6 m
