Horizontal Projectiles
Horizontal projectiles are used for objects that are thrown or launched horizontally from their starting point. The velocity of horizontal projectiles never changes, so the initial velocity will also be that objects final horizontal velocity. When you're looking at an object thrown horizontally, that means the objects vertical velocity will remain at 0. In other words, no matter the velocity of the ball being thrown, an object dropped from the same weight will land on the ground at the same time the object thrown will.
If a pitcher and batter were to experiment with this idea, the pitcher would throw the ball as fast as he possibly could, and the batter would drop the bat from the same height that the pitcher released the ball at, and due to the basic concepts of horizontal and vertical projectiles, they would both land on the ground at the same time.
Q.) Does the mass of an object being dropped change the results of an experiment like the one above?
No, when vertical initial velocity is at 0, it will always land at the same time as object with horizontal velocity.
Q.) Which will hit the ground first, a bullet dropped, or a bullet launched, and why?
They will land at the same time because one has horizontal velocity and one has no vertical velocity.
