Question

A body moves from origin 4m towards east then 4m towards North then 3√2m towards North east. If total displacement is x√2m find x​

Answer 1

Explanation:

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
