If a stone is to hit at a point which is at a distance `d` away and at a height `h` (see fig) above the point from where the stone starts,then what is the value of initial speed `u` if the stone is launched at an angle `theta`?

A stone is projected from a point on the ground in such a way so as to hit a bird at height 3h and could attain a maximum height 4h above the ground. If at the instant of projection, the bird flies away horizontally with speed 10 ms^(-1) and the stone still hits the bird while descending, then the horizontal velocity of stone is
