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`?

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 ? .

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

If a stone is to hit at a point which is at a horizontal distance 100 m away and at a hight 50 m 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 45^(@) ?

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 dropped from a rising balloon at a height of 76 m above the ground and reaches the ground in 6s. What was the velocity of the balloon when the stone was dropped?

A man standing on the edge of a cliff throws a stone straight up with initial speed (u) and then throws another stone straight down with same initial speed and from the same position. Find the relation of the speeds. The stones would have attained when they hit ground at the base of the cliff.
