A cannon ball is fired from a cannon horizontally

At the same time you drop a cannon ball of the same weight from the same height. Which cannon ball will hit the ground first?

Does it depend on speed of cannon ball fired? Probably the one you drop though I think

the one you drop, the one from the cannon travels laterally so due to the spherical nature of the earth will have further the drop (assuming its on "flat" ground)

No its always the one you drop, the speed just increases the differential. And at a high enough velocity it just goes into orbit

You left out one important detail, speed / acceleration of cannonball fired.

Horizontal wud land at same time

Fired above horizontal will land after
Fired below horizontal will land first

Youve given the ball zero vertical acceleration if you fire horizontal

if firing in earth's atmosphere the minuscule amount of lift generated will make the fired one land slightly later

Well, your honours degree left you a fukkin moron.
A cannon is about 4 feet off the ground. You drop a cannon ball from four feet I can guarantee you it's hitting the ground sooner than a cannon ball being accelerated across the ground horizontally. Is this seriously even debatable?

What OP left out because he's also a fukkin moron is a chit-ton of variables that make this a math problem. Instead, because you're both dipchits, it's a logic problem that has evaded both of you.

2:1 Mathematics degree here, and you're wrong. Speed matters when cannonball is fired horizontally, because F=ma.

When cannonball is dropped, equation becomes F=mg because gravity.

When fired from horizontal, acceleration must be taken into account because that will have an effect on how long the projectile will travel before it hits the ground.

Basic projectile ballistics.

Horizontal is in a different plain though, and does not effect the vertical forces except for any lift generated

Are you kidding me?

Fuk me a bunch of dumbasses ITT.

Do this experiment.

Fire a M1911 handgun horizontally, and at the same time drop a bullet from same height. Guarantee you the bullet dropped will hit the ground first.

For example, if the cannonball comes close to escape velocity, vertical forces will virtually remain the same, but the time it hits the ground will be longer than for the other cannonball.

It affects how FAR horizontally it travels but not the time it takes to hit the ground
Again only applies if fired exactly horizontal

Wrong. The faster the initial speed of the projectile, the longer it will travel and the more time it will take to hit the ground.
