Rain rain go away..little Johny wants to ski

eure in the third case (man on extreme right) is he stationary? and the observed dirn of rain in that case is down the incline?

based on the other two figs. the hori comp of rain is 5m/s towards right.

fig. in below post

if the answer to my question is yes then the vert. comp of the rain is 5/√3 because then the direction of rain is what is given in the fig (30° with horizontal)

absolutely rite....
