Question

person moves 303 m towards North and 20 m towards East and finally 10 3 m towards South The magnitude of displacement of the person from the origin is

Answer 1

Answer:

30m North

20m East

and the 30

2

SW can be rewritten as 30m in south and 30m in West

because south and west being at 90

0

result

in

30

2

+30

2

=303

20

so at last we have following data that in south X

S

=303m+north=303m+(−303m)=0,

negative becasue north is opposite to south.

and in West we have X

W

=30m+east=30m+(−20m)=10m

so the displacement is 10m due west
