The horse's displacement is 0 m.
Explicación
## Step 1Displacement is a vector quantity that refers to the shortest distance between the initial and final position of a point. It is the straight line distance between the starting point and the ending point, and it also includes the direction of that line.## Step 2In this problem, the horse runs around a circular track and returns to its starting point. The horse runs clockwise from the start line back to the start line, then turns back and goes counterclockwise back to the start line again.## Step 3Since the horse ends up at the same position where it started, the displacement is zero. This is because the horse's final position is the same as its initial position.
