Question

In a long distance race, the athletes were expected to take four rounds of the track such that the line of finish was same as the line of start. Suppose the tength of the track was$200\mathrm{m}$. What is the displacement of the athletes when they touch the finish line?

Answer 1

Step 1: Given Data:

Length of the track, $=200m$

Four rounds were taken by athletes.

Step 2: Total Displacement:

As we know, displacement is the shortest path between the initial point and the final point.

So for one round, in this case, finish point and starting points are the same, so $Displacement=0$

And since, four-round were taken by athletes. $Displacement=4\times 0\Rightarrow 0m$

Hence, total displacement to be covered by the athletes, $=0m$
