Answer:
The magnitude of the displacement is [tex]H = 14.14 \ km[/tex]
Explanation:
From the question we are told that
The distance of the car to north is d = 10 km
The distance of car to the west is w = - 10 \ km
The negative sign is because the direction is west
Generally applying Pythagoras theorem , the displacement is
[tex]H = \sqrt{d^2 + w^2}[/tex]
=> [tex]H = \sqrt{(10)^2 + (-10)^2}[/tex]
=> [tex]H = 14.14 \ km[/tex]
