Sahay Sir > Question Answers > A boat moves relative to water with a velocity which is n=2.0 times less than the river flow velocity. At what angle to the stream direction must the boat move to minimize drifting?
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 maximum anlgle by which the window pane can be raised outward without letting rain water enter into the car when it races through rain ( falling vertically at 20 kmph) at 60 kmph.
