The sprinter's displacement after she returns to her initial position is 0 m.

option A is the correct answer.

What is displacement of the sprinter?

The displacement of the sprinter is the change in the position of the sprinter after the race. It is also the shorted distance between the initial position of the sprinter and the final position of the sprinter.

Mathematically, the formula for the change in the position of the sprinter is given as;

Δx = xf - xi

where;

  • xf is the final position of the sprinter
  • xi is the initial position of the sprinter

when the sprinter starts from point A of a circular track and returns to the starting point A, that is one lap. When the sprinter moves again and returns to the same starting point A, that is two laps.

From the above illustration, the final position of the sprinter is equal to the initial position of the sprinter.

Δx = xf - xi

xf = xi

Δx = 0 m
