If a stone is to hit at a point which is at a distance `d` away and at a height `h` (Fig. 5.200) 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

`d/(sin theta) sqrt((g)/(2(d tan theta - h)))`

B

`d/(cos theta) sqrt((g)/(2(d tan theta - h)))`

C

`sqrt((gd^2)/(h cos^2 theta))`

D

`sqrt((gd^2)/((d - h)))`
