My friends are retarded and think that things moving sideways will take longer to hit the ground than an object in horizontal equilibrium.
So, if a bullet is shot from a gun 100% horizontally, and a bullet is dropped at the same height and time, will they both hit the ground at the same time?

Yes. Newton's F=ma is a vector equation. The gravitional force is a vertical vector. It therefore only effects the vertical component of the velocity vector. It's all about vectors, man.

Yes, but only if you ignore the air. A real bullet, fired in real air, in a real experiment, may take longer or shorter to fall the same distance. If you do the experiment with a ball bearing fired by a spring gun at low velocity, and everything is perfect, you should get very nearly equal times.

Both bullets will hit at the same time.

If the ground you were standing on were perfecty flat, then yes, they would hit at the same time

Yes, drag acts in one direction (x axis) and gravity acts in the other direction (y axis)
