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 ball is thrown from a point on ground and it lands on same level at distance of

A ball is projected from a point at two different angles with the same speed U and land at the same point in both the cases

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.

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.

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 ball is projected from the ground with speed u at an angle alpha with horizontal. It collides with a wall at a distance a from the point of projection and returns to its original position. Find the coefficient of restitution between the ball and the wall.

A ball is projected from the ground with speed u at an angle alpha with horizontal. It collides with a wall at a distance a from the point of projection and returns to its original position. Find the coefficient of restitution between the ball and the wall.

A ball is projected from a point on a smooth horizontal floor at an angle theta with the horizontal . Speed of projection is u . Ball collides with the floor several times . Find the total time and horizontal distance covered by the ball .
