Consider a wedge rod system in which rod of length L is moving vertcially downwards without tilting with constant speed v. The sitatuin at `t = 0` is shown in the figure. The surface of the wedge is parabolic and has an equation `y = x^(2)`. Find the speed of wedge at `t = 0`. (Assume that the contact between the rod and wedge is not lost).
