In a very popular lecture demonstration, a projectile is fired at a falling target in such a way that the projectile leaves the gun at the same time the target is dropped from rest, as in the Figure. Let us show that if the gun is initially aimed at the target, the projectile will hit the target. Target t = 0 ½gt2 Xr tan 6, Line of sight
