A target situated on a hill can be seen from the foot at angle α above the horizontal .The distance of the target along the horizonal is R. if a shell is fired from the foot at an angle β with the horizontal, find the velocity required for it to strike the target.

A projectile is required to hit a target whose coordinates relative horizontal and vertical axes through the point of projection are (α it is impossible to hit the target if β). If the gun velocity is 2gα ​
