with reference to the origin fixed to his initial position.

Answer 1

Answer:

The displacement vector is

$80\hat i+50\hat j+50\hat k$

Explanation:

If we take East direction as x-axis, North direction as y-axis and up the ladder direction as z-axis then the displacement vector can be written as

$\vec d=80\hat i+50\hat j+50\hat k$

This is the required displacement vector

Hope this helps.
