A man is running up an inclined plane ( making an angle theta with the horizontal ) with a speed u. Rain drops falling at an angle alpha with the vertical appear to the man as if they are falling at an angle of 45^(@) with the horizontal . The speed of the rain drops is

A man moves on a cycle with a velocity of 4 km/hr. The rain appears to fall on him with a velocity of 3 km/hr vertically. The actual velocity of the rain is

A man running at a speed of 5 km/h finds that the rain is falling vertically. When the stops running, the finds that the rain is falling at an angle of 60^(@) with the horizontal. The velocity of rain with respect to running man is
