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 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 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 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^(@) ?

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^(@) ?

If a tower of height 'h' is observed from a point with a distance 'd' and angle ' theta ' , then express the relation among h,d, theta .

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 horizontally with the velocity u = 15m/s from a tower of height H = 25 m. Find (i) the time during which the stone is in motion , (ii) the distance from the tower base to the point where the stone will touch the ground (iii) the velocity v with which it will touch the ground (iv) the angle theta the trajectory of the stone makes with the horizontal at the point stone touches the ground (Air resistance is to be neglected). (g=10ms^(-2)) .
