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 projected from the ground in such a direction so as to hit a bird on the top of a telegraph post of height h and attains the maximum height of 2h above the ground. If at the insatant of projection, the bird were to fly away horizontally with a uniform speed, find the ratio between the horizontal velocity of bird and the horizontal component of velocity of stone, if the stone hits the bird while descending.

A particle is projected from a point on the level ground and its height is h when at horizontal distances a and 2 a from its point of projection. Find the velocity of projection.

Particle is projected from the ground at a certain angle with horizontal . If particle takes time T to hit the ground again , then maximum height of the projectile is

A stone is projected at an angle alpha to the horizontal from the top of a tower of height 3h If the stone reaches a maximum height h above the tower, then calculate the distance from the foot of the tower where particle strikes the foot of the where particle strikes the ground.

A particle is projected from ground with speed u and at an angle theta with horizontal. If at maximum height from ground, the speed of particle is 1//2 times of its initial velocity of projection, then find its maximum height attained.

A ball is thrown form a point on a ground at some angle of projection. At the same time a bird starts form a point directly above this point of projection at a height h horizontally with speed u . Given that in its flight ball just touches the bird at one point. Find the distance on ground where ball strikes

A stone is dropped from the top of a tower. If it hits the ground after 10 seconds, what is the height of the tower?

A stone projected vertically upwards from the ground reaches a maximum height h . When it is at a height (3h)//(4) , the ratio of its kinetic and potential energies is

A stone is projected at an angle alpha to the horizontal from the top of a tower of height 3h. If the stone reaches a maximum height 'h', above the tower, show that it reaches the ground at a distance 6h cot alpha from the foot of the lower.
