Answer:
D = 14.31 m
Explanation:
It is given that,
Displacement due east is 12 m
Displacement due north is 5 m
Displacement in vertically upward direction is 6 m
We need to find the magnitude of the sum of these displacements. We know that, vertically upward, east and north are mutually perpendicular direction. So, the resultant is given by :
[tex]R=\sqrt{12^2+5^2+6^2} \\\\R=\sqrt{144+25+36} \\\\R=14.31\ m[/tex]
So, the magnitude of the sum of these displacements is 14.31 m.
