If a stone s thrown at a point which is at a distance d away and at a height h above the point from where the stone starts, then what is the value of initial speed u if the stone is lauched at angle `theta`?

A

`(g)/(cos theat)sqrt((d)/(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)))`

A person can throw a stone to a maximum distance of h meter. The greatest height to which he can throw the stone is:

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

A stone is thrown with a speed of 10 ms^(-1) at an angle of projection 60^(@) . Find its height above the point of projection when it is at a horizontal distance of 3m from the thrower ? (Take g = 10 ms^(-2) )

A stone is thrown with a velocity v at an angle theta with the horizontal.Its speed when it makes an angle beta with the horizontal is

A stone is thrown at an angle theta to the horizontal reaches a maximum height H. Then the time of flight of stone will be:
