$\huge\underline\mathfrak{Question-}$

On a certain day rain was falling with a speed of 35m/s wind started blowing after some time with a speed of 12m/s in east to west direction should waiting at bus stop . Find V.

There it should be 12 instead of 17.

$\huge\underline\mathfrak{Answer-}$

Given ;-

(i) Speed Means ......V²r = 35 m/s

(ii) Speed Means ...... V²w = 12 m/s

We know that ;-

$= > v = \sqrt{v^{2}r + v^{2}w}$

$= > v = \sqrt{(35)^{2} + (12)^{2} } = \sqrt{1369}$

$= > v = 37$
