A projectile is projected and it takes `9 s` to reach in the horizontal plane through the point of projection. In its path it passes a point `P` after `4 s`. The height of `P` above the horizontal plane is

" The velocity of a projectile at point of projection is " 5hat i+4hat j " its velocity at the point of return to the same horizontal plane is "

A projectile is fired at an angle of 45^(@) with the horizontal. Elevation angle of the projection at its highest point as seen from the point of projection is

A projectile is fired at an angle of 45^(@) with the horizontal. Elevation angle of the projection at its highest point as seen from the point of projection is

A projectile is fired at an angle of 45^(@) with the horizontal. Elevation angle of the projection at its highest point as seen from the point of projection is

A projectile is aimed at a mark on a horizontal plane through the point of projection and falls 6 m short when its elevation is 30° but overshoots the mark by 9 m when its elevation is 45^@ . The angle of elevation of projectile to hit the target on the horizontal plane is :

When a projectile os projected at an angle with the horizontal, find the angle of projection for its maximum horizontal range and find the correspondg height achieved by the projectile?
