Given : For a person walking on a horizontal road with 5 KMPH it appears to rain with a velocity 13 KMPH. it is raining vertically downwards,
To Find : the actual velocity of rain
Solution:
Let say the actual velocity of rain = x kmph
person walking on a horizontal road with = 5 kmph
Relative Velocity = √x² + 5²
it appears to rain with a velocity 13 kmph
Equate both
=> √x² + 5² = 13
=> x² + 25 = 169
=> x² = 144
=> x = 12
the actual velocity of rain = 12 kmph
