Answer:
0m
Step-by-step explanation:
The displacement of a runner when he completes one lap round track in 100s is 0m.
Displacement is the distance covered in a specific direction. This quantity is referred to as a vector because it has both magnitude and direction.
- Displacement takes into account the starting and finishing position of a body.
- Also, the direction from start to finish gives us the vector dimension of the body.
- Therefore, when the runner completes a lap, the start and finishing point is the same
- The displacement is 0m
