Given:-

  • Rain is falling vertically downward with a speed of 35 m/s.
  • Wind start blowing with speed of 12 m/s from East to West direction.

To Find:-

  • The angle at which the umbrella should be hold by the boy so that he won't receive any rain.

Concept used:-

  • The boy has to hold the umbrella in direction of velocity of rain w.r.t velocity of the wind.

Solution:-

Let the angle be A.

So, tanA = Velocity of wind/velocity of rain

tanA = 12/35

tanA = tan(19.6°)

Comparing, we get

A = 19.6° .

So, the boy should hold the umbrella at an angle of 19.6° from vertical toward east.

So, the boy should hold the umbrella at an angle of 19.6° from vertical toward east.So, the boy should hold the umbrella at an angle of 19.6° from vertical toward east.[Wind is coming from East to West]
