A person initially at rest starts to walk 2 m towards north, then 4 m towards east, then 5 m towards south and then 3 m towards west. What is the position vector of the person at the end of the trip?

Text Solution

Verified by Experts

As shown in the Figure, the positive x axis is taken as east direction, positive y direction is taken as north After the trip, the person reaches the point P whose position vector given by
`vecr=-2hati-3hatj`
The displacement direction is south west.
