A stone is projected from the pont of a ground in such a direction so as 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 brid were to fly away horizontally with a unifrom speed , find the ratio between the horizontal velcoities of the bird and the stone , if stone still hits the bird while descending .

Explanation

`(v)/( u cos theta) = (2)/(sqrt(2) + 1)`
