Question

A althete runs a circular path of radius 50km it take 50sec to compete the round calculate distance and displacement

Answer 1

Circumference=2πr=2×3.14×50=314m

50sec for half round, so 100 sec =full round,

a) Distance=2πr=314m

b)displacement= 0

bcz he came to start point again therefore displacement = 0

c) speed =distance/time

s=314/100

s=3.14ms-¹

Hope it will help you.

Please mark my answer as brilliant.
