Answer
Given.
speed of rain is 35m/
Speed of wind is 12m
The resultant velocity of raindrops will be the vector sum of the raindrop speed (vertical)
and the horizontal wind speed.
The magnitude of the resultant velocity of the raindrops is:
(123 +354) = 37m/sec
the direction of the resultant velocity vector with the vertical
=tan k pawer -1 (12/35)
) = 18.92.
