An aircraft is flying horizontally with velocity v. It moves within a band of rain that falls uniformly vertically at speed w. The cockpit has two transparent surfaces: horizontal top and front screen inclined at an angle $\alpha$ to the horizontal (Fig.). Each of the surfaces has an area of S. Find the ratio of the number of drops of water falling per unit of time on the front glass, to the number of drops falling per unit time on the top glass.
