Michael walks 10m north, 3m west, 5m south, 12m east, and then stops to catch his breath. What is the magnitude of his displacement from his original point?

I don't know but it sound like a long walk I don't blame him for acting his breath

From (0,0),  we have the following sequential displacements :

(0,0) + (0, 10)  = (0, 10)

(0,10) + (-3, 0)  = (-3, 10)

(-3,10) + (0, -5)  = (-3, 5)

(-3, 5) + (12, 0)  =  ( 9, 5)

The distance (displacement)  from the original point is

sqrt ( 9^2 + 5^2 )   =  sqrt ( 81 + 25)  =  sqrt (106) ≈ 10.3 m
