Question

Rain is falling vertically downwards with velocity a person is walking on a road with velocity holds his umbrella in the direction of
1) Relative velocity of rain w.r.t to him
2) Relative velocity of man w.r.t to rain
3) Both 1& 2
4) Only 2

Answer 1

Answer:

The described situation is shown in the given figure.

Here, v  

c

​  

= Velocity of the cyclist

v  

r

​  

 = 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=v  

c

​  

/v  

r

​  

=10/30

θ=18  

o

 

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