The resultant displacement that John Traveled is; 5 meters
<h3>How to find the displacement?</h3>
We are told that;
- He walked 3 meters north
- Then he walked 4 meters east
Distance is defined as the total movement of an object without any regard to direction. Whereas, Displacement is defined as the change in position of an object.
Thus, distance would have been 3 + 4 = 7 m. However, we are dealing with direction here as regards displacement and as such this will be gotten by Pythagoras theorem.
Displacement = √(3² + 4²)
Displacement = 5 meters
Complete question is;
John walks 3 m north and then 4 m east. What is the resultant displacement?
