1gm water is 10^-3kg. g is about 10, actually 9.81.h = 2000 metres.GPE = mgh = 10(^-3)kgx10x2x(10^3) =n about 20 Joules ???using kinematic equation ... v^2=u^2+2as where drop starts at rest, u= 0.v=sqroot(2x10x2000) m/sv=sqrt (40 000)I may have got the zeros confused here, 'cos it looks as though it should come out as an "easy" number.This calculation assumes NO air resistance so that TERMINAL VELOCITY is not relevant.

Answer: 24.4 degrees to the vertical
Explanation:
Vertical component of raindrop speed = 11m/s
Horizontal component of wind = 5m/s
In this case, all we have to do is to use trigonometric ratios of angles to sides as in a triangle
Doing this, we see that
tan (theta) = 5/11
(Where theta is the angle made with the vertical by the rain after impact)
Tan being opposite/adjacent
Arc sin (5/11) gives us 24.44 degrees to the vertical
