Answer:
Distance = 1256 m
Displacement = 0
Step-by-step explanation:
Distance :
Distance may be defined as the actual length between two points along its path.
It is a scalar quantity and its value can be positive or zero.
Displacement :
Displacement is defined as the shortest length between two point , i.e. between the initial point and the final point.
It is a vector quantity and it has values which can be either positive or negative or zero.
From the question, the diameter of the circular track is, r = 200 m
∴ Distance travelled by an athlete is = circumference of the circular track
= 2πr
= 2 x 3.14 x 200
= 1256 m
Displacement = 0 (since the original point coincides with the final point).
