Question

13. A hiker walks 200 m west and then walks 100 m north. In what direction is her resulting displacement?

Answer 1

100m north west   is the answer                                      

Answer 2

Answer:

Resultant displacement of the hiker is 223.60 meters in northwest direction.

Explanation:

It is given that,

Distance covered in west direction, d₁ = 200 m

Distance covered in north direction, d₂ = 100 m

We need to find the resultant displacement. The distance covered can be solved using Pythagoras theorem as :

$d=\sqrt{d_1^2+d_2^2}$

$d=\sqrt{(200)^2+(100)^2}$          

d = 223.60 m

So, the resultant displacement of the hiker is 223.60 meters in north west direction. Hence, this is the required solution.
