Answer:
Resultant displacement = 5 m
Explanation:
A student walks 3 m north and 4 m south.
We need to find the magnitude of the resultant displacement for the student.
He walks in the North and then in South direction. The magnitude of resultant displacement is given by :
[tex]D=\sqrt{3^2+4^2} \\\\D=\sqrt{9+16} \\\\D=5\ m[/tex]
So, the magnitude of the resultant displacement for the student is 5 m.
