rain pouring down at an angle alpha with the vertical has a speed of 10 m/s. a girl runs against the wind with a speed 8 m/s and sees that the rain makes an angle beta with the vertical. Then the relation between alpha and beta is? - hint - the answer is => tan beta = (8+10sin alpha)/(10 cos alpha) please help me out ....
