A stone is projected from the point of a ground in such a directed as so to hit a bird on the top of a telegraph post of height h and then attain the maximum height 2h above the ground. If at the instnat of projection, the bird were to fly away horizontally wit a uniform speed, find the ratio between the horizontal velocities of the bird and the stone, if the stone still hits the bird while descending.

1.	A stone is projected from the point of a ground in such a directed as so to hit a bird on the top of a telegraph post of height h and then attain the maximum height 2h above the ground. If at the instnat of projection, the bird were to fly away horizontally wit a uniform speed, find the ratio between the horizontal velocities of the bird and the stone, if the stone still hits the bird while descending.
