Question

What is the net displacement for a to and fro motion

Answer 1

Answer:

Track length of the swimming pool =50m.

So, swimming forward and coming back, the swimmer covers a distance of 100m and displacement is 0.

Making the next to-and-fro round, the swimmer covers total distance of 200m and still the net displacement is 0.

For the last 50m, the swimmer reaches the farthest end of the pool.So, the displacement = length of the track =50m.
