A zoologist standing on a cliff MJ tranquilizer gun at a monkey hanging from a distance tree branch. The barrel of the gun is horizontal. Just as the zoologist pulls the trigger, the monkey lets go and begins to fall. Will the dart hit the monkey? Ignore air resistance.

A displacement equivalent to the movement of a projectile occurs. The difference is that the monkey does not have the horizontal component that the Projectile does. Due to gravity, both are subject to the change in speed caused by acceleration due to gravitational attraction.

Both objects fall at the same rate, therefore, the projectile will impact the monkey, in the same position in which the Zoologist calculated its impact.
