Rain is falling vertically with a speed of 15 m/s. A woman rides a bicycle with a speed of 5 m/s in east to west direction. What is the direction in which she should hold her umbrella?
Answers
Explanation:
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.
Question:Rain is falling vertically with a speed of 30ms
Rain is falling vertically with a speed of 30ms −1
Rain is falling vertically with a speed of 30ms −1 . A woman rides a bicycle with a speed of 10ms
