Discussion
A hunter on the ground wishes to shoot a bird on a tree at a distance with his rifle. He has to point the rifle
Answer: B
He must point at a higher elevation than the bird.
The bullet begins to fall under gravity the moment it leaves the barrel, so it follows a parabola and drops below the line of sight. Aiming slightly high compensates for that fall over the flight time - which is why rifle sights are zeroed for a particular range.
