An Athelice complete :Round of a circular track of diameter 200m in base Distance travelled by athletes And displacement

Distance = 1256 m

Displacement = 0

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).

attach the statements so i can answer : )

that would be because of both gravity and friction. so     c
