Answer 1

Explanation:

ald Rain is is calling at angle of 37°man having speed 5okm, and having an umbrella in his hand walking with speed of 40km/h. Find the relative velocity rain Also find the value of angle at which the man has to umbrella in of rain open his umbrella ?

Answer 2

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.
