Question

What is your displacement if you walk 100m north, 20m east, 30m south, 50m west and then 70m south?

Answer 1

You moved west by 30m from original standpoint.

Answer 2

Our displacement from initial point is 30 m south.

Step-by-step explanation:

AB = 100 m (North)

BC = 20 m (East)

CD = 30 m (South)

DE = 50 m (West)

EF = 70 m (South)

FA = ?

Here in an image, our initial point was point A and final point was F.

Let the point at which AB is intersect by line DE be G.

From the image : EG = FA

EF = ED - EG

= 50 m - 20 m = 30 m

So, FA = 30 m

Our displacement from initial point is 30 m south.
