How to solve
Solution
Let us assume that the rod one end is at a distance X and other end is at a distance Y from the horizontal and vertical direction. Basing on the basic rule of trigonometry, we can find the relation of them with the length.
These are the displacements and we are interested with speeds. We know that the rate of change of displacement is the velocity and hence we shall differentiate the equation.
