Answer 2

Answer:

The described situation is shown in the given figure.

 Here, vc= Velocity of the cyclist

vr = Velocity of falling rain

In order to protect herself from the rain, the woman must hold her umbrella in the direction of the relative velocity (v) of the rain with respect to the woman.

tanθ=vc/vr=10/30

θ=18o

Hence, the woman must hold the umbrella toward the south, at an angle of nearly 18 with the vertical.
