If rain drops are falling with velocity of 12m/s at an angle of 30° with the vertical. With what possible speed(s), a man should move in horizontal direction so that rain drops hit him at an angle of 45° with the horizontal.

This shows that the horizontal component of rain =8 km/hr as the relative velocity of the rain has only a vertical component with respect the man.
Vx=8km/hr2nd
case → VRM
=V R-VM
=(8↑−V y ↑)-12↑=-4↑-VY↑
tan30° =VY 43
km/hr
⇒∣V∣=47
km/hr
Velocity of Rain =8 km/hr↑−43
km/hr↑
⇒tanα= 32
from vertical
