Question

(4) x:= -
X;= -4/11
13 A particle moves 24 m south and then 9 m west
and finally 18 m vertically upwards. The resultant
displacement of the particle is approximately
(1) 25 m
(2) 40 m
(3) 24 m
(4) 31 m​

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
