A body projected from a point `O` at an angle `theta`, just crosses a wall `y` `m` high at a distance. `x` `m` from the point of projection and strikes the ground at `Q` beyond the wall as shown, then find height of the wall

A body projected just crosses a wall of 4m height,at 6m distance from the point of projection and it hits the ground at 12m away from the wall. The angle of projection is nearly

A ball projected from ground at an angle of 45^(@) just clears a wall infront. If point of projection is 4m from the foot of wall and ball strikes the ground at a distance of 6m on the other side of the wall, the height of the wall is

A ball is projected at an angle 45^(@) with horizontal. It passes through a wall of height h at horizontal distance d_(1) from the point of projection and strikes the ground at a horizontal distance (d_(1) + d_(2)) from the point of projection, then

A ball is projected from ground with a speed of 20ms^(-1) at an angle of 45^(@) with horizontal.There is a wall of 25m height at a distance of 10m from the projection point. The ball will hit the wall at a height of

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.
