Question

a person travel a distance of 3 kilometre along a straight line in north direction then he travel to 2kilometre in West direction and then 5 kilometre in south direction the magnitude of the displacement of the person would be​

Answer 1

Answer:

IA person walked 3 km in north, 2km west and 5 km in South. Then, the map becomes like:

Then now we have .

P=5–3=2km b=2km

So H^2=P^2+B^2,

H^2= 4+4

H^2=8

Or H=√8

The displacement travelled by person is 2√2 km or 2.82km
