A runner runs around a circular track with a circumference of 1000 meters.?

Question

Find the distance covered and the displacement made by the runner.

Answer 1

I'm assuming you mean the runner makes one complete lap around the 1000 meter long track and then stops at the point where he/she began running. If so:

Displacement is the vector from the initial point to the final point. Since the runner ends where he/she begins, the vector has zero length, and the displacement is zero.

Distance is the length of the path taken by the runner, which is 1000 meters.
