Question

a person moves to East at Speed 6 m/s and feels the wind is blowing south at 6m/s what will actual velocity find blow
A)6 root 2 south-east direction
B)6 root 2 south-west direction
C) 2 in S-E direction
D)2 in S-W direction
​

Answer 1

Answer:

B

Explanation:

let the east direction be the x axis

so we can imply that velocity of the person is '6i' in the vector form

wind is blowing to South means according to our graph it is blowing to the negative direction of y axis

thus speed of wind is '-6j'.

now relative velocity of wind w.r.t person is -6j-6i

in the image I have attached the resultant is R which will be 6√2 (by solving by prallelogram law)

which is in South West direction
