On a rainy day, a man is running on a hilly terrain in such a way that he is always finding the rain
drops hitting him vertically. It is assumed that rainfall is uniform in the whole terrain from O to E.
When the man was at rest on stretch OA, he found the rainfall at an angle of 30° with the vertical
