Question

For a man running with a speed v . wind apears to have a velocity v and inclinatin 120^o with him . find orignal velocity a]v b]2v c] v/2 d]3v (ANS IS OPTION a].... BUT PLS GIVE ME THE ANSWER WITH PROPER EXPLANATION)

Answer 1

sorry but I don't know the answer

Answer 2

Answer: V

Explanation:

Velocity of wind with respect to man = velocity of wind - velocity of man

Therefore velocity of wind = relative velocity + velocity of man

x = ✓v^2 + x^2 -2ax (-1/2) + v

Since cos 120 is -1/2

x = v - x + v

2x = 2v

I hope it helps... And everyone understood
