WL#113

Problem no 113 - part 1

Calculate a minimum angle of a shot to aim a target placed on the roof 3 meters above a ground and moved 2 meters away of its edge. The wall is 10 meters from the shooting point. Air drag must be skipped, it is also assumed that the body is a point with no geometry which could touch an edge of a roof, but obviously it cannot also get through the wall.
