Question

3. A person moves 30 m north and then 20 m towards east and finally 30✓2 m in South west direction. The displacement of the person from the origin will be :​

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

=30

2

so at last we have following data that in south X

S

=30m+north=30m+(−30m)=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
