Question

A man walks 30 m north then 20 m towards east and then 30 root 2 m towards south west what is displacement

Answer 1

Answer:

Hey bro I have solved this

Explanation:

The position of person from origin is 10 m West.

Explanation:

Given that,

A person moves 30 m North then 20 m east than 30 root 2 meter southwest.

The movement along north direction, Vector OY =

The movement along east direction, Vector YX=

Movement along south west direction, XZ

Vector XZ==30i + 30j

Using triangle vector law,

OX = 20i + 30j

XZ = 30i + 30j

In triangle XZO, OZ is resultant from origin.

OZ = OX-XZ

OZ = 20i + 30j - 30i - 30j

OZ = -10i

Hence, The position of person from origin is 10 m West.
