Given:
Diameter of circular track = 200m time to complete = 40s
Formula:
Circumference of circular track = d. π m
speed = distance/time
Circumference of the track = d.π
= 200 × 3.14 = 628m
speed = \(\frac{628m}{40s}\) = 15.7 ms-1
Distance covered in 2 min 20 s = speed × time
In the given time athlete covers 31/2 rounds =
2198 m
The final position of athlete is as shown in figure (A – initial position, B – final position)
∴ Displacement = Distance × time
= 200 m
