Question

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

Answer 1

Distance moved / relative speed of the rain = 0.15

Explanation:

Given: On A rainy day a man is running On a hilly terrain in such a way that he is always finding the rain hitting him vertically .It is assumed that the rainfall is uniformed in the whole terrain from O to E when the man was at rest on stretch OA he found the rainfall at an angle 30 degree with the vertical.

Note: The question is incomplete as to what we have to find. So interpreting the maximum information we can given the situation.

Solution:

Cos 30 = distance moved / relative speed of the rain

 Cos 30 = 0.15

So distance moved / relative speed of the rain = 0.15
