Question

14. A person travels 20m East, Sm North and finally 8V2 North-West. Find the displacement of
person?
1) V284 m 2) 298 m
3) 300 m
4) 400 m​

Answer 1

Step-by-step explanation:

Towards north is X

N

=8m and towards east is X

E

=20m

Now the 8

2

m towards North-west can be rewritten as 8×

North+

West)=8mNorth+8mWest

so the net displacement in east will be X

E

−8m=12m

so the net displacement in North will be X

N

+8m=16m

now we have to calculate its vector sum as North and EAST are perpendicular to each other so net

displacement will be d=

+16

=20m
