Four rods each of length I have been hinged to form a rhombus. Vertex A is fixed to a rigid support, vertex C is being moved along the X− axis with a constant velocity v as shown in the figure. The rate at which vertex B is approaching the x− axis at the momentum the rhombus is in the form of a square is

A glass wind screen whose inclination with the vertical can be changed is mounted on a car. The car moves horizontally with a speed of 2m/s. At what angle α with the vertical should the wind screen be placed so that the rain drops falling vertically downwards with velocity 6m/s strike the wind screen perpendicularly?
