Answer:
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.
