Question

When a 10,000-m runner competing on a 400-m track
crosses the finish line, what is the runner’s net
displacement? Can this displacement be zero? Explain

Answer 1

Answer:

yes the displacement will be zero

Explanation:

Because displacement is the shortest path between initial and final points. and here is the difference between the initial and final point is zero so the displacement will be zero

Answer 2

Yes, displacement will be zero.

• First of all, let's define Displacement:

• DISPLACEMENT IS THE SHORTEST LENGTH BETWEEN STARTING AND STOPPING POINT OF AN OBJECT.

Now, when the runner competes in 400 metre race track, he/she starts from the starting line and then reaches the finish line where he/she stops.

• That means that the starting and stopping points are same (i.e. initial and final position is same).

• So, displacement will be zero.
