How to calculate the angle of incidence of the projectile (including air resistance)?

Is it possible to calculate the angle of incidence of the projectile flying on a ballistic trajectory? (the angle in the moment of encounter with the earth)
Shot and the fall of the projectile is on the same horizontal plane.

In principle, interested in a General formula, but the specific case is this:

Upd: the Air should be considered.

The angle of incidence equals the angle of reflection. Ugh: the angle in the moment of encounter with the earth is equal to the angle at the moment of farewell with the earth.5c99194d36fe2137115683.gif
The problem is that we shoot in the air :) - elian_Remp commented on March 19th 20 at 08:37
@elian_Remp, and the General formula is not. For a specific gun, a specific type of weapon has a table of test results, taking into account all significant, the type of wind speed. From the tables we can construct a formula approximating them.
But how will be different the behavior of the projectile from a rifled gun, from the feathered projectile from a smoothbore? - Linnea.Willms85 commented on March 19th 20 at 08:40
It's about the vacuum of space. In the airspace Googly computing siacci, the table and the table of Otto, since all approximations in the calculations to the realities of the based on tabular values of air resistance depending on the shape of the projectile - Beatrice31 commented on March 19th 20 at 08:43
@Linnea.Willms85, there is already an internal PS. when will be added) - Beatrice31 commented on March 19th 20 at 08:46
Uzhos =)
Thank you all! - elian_Remp commented on March 19th 20 at 08:49
