A car window pane of length 25 cm is hinged at the top and 5 cm of its lower portion is covered by a fixed pane. calculate the max angle by which the window pane can be raised outward without letting rain water enter in to the car when it races through rain at 60 kmph. The rain drops are falling vertically at 20 kmph
