Question

a person moves 3m due north, then truns towords east and moves again 4m . the displacement of the person​

Answer 1

Answer:

5 m

Explanation:

movement 1 : 3m north,

movement 2 : 4m east

then displacement is the shortest distance between the point of origin and the last point.

if we draw the movement , the displacement will be the hypotenuse of the triangle formed with a = 3 and b = 4

so, hypotenuse =  $\sqrt{a^{2}+b^{2} }$

                          = $\sqrt{3^{2}+4^{2} }$

                          = $\sqrt{9+16}$

                          = $\sqrt{25}$

                          = 5 m

Answer 2

Answer:

The Answer Is 5 Metres

Explanation:

Since the person moves 3m North, and then turns and walks 4m East, it will become a right angle triangle(as seen in the image). So, the hypotenuse of the triangle is the displacement, which is the distance between point A and point C. We will calculate the hypotenuse using Pythagoras Theorem (see in image). And thus, the answer will be 5 Metres.
