My carrying capacity is 30000.
This truck weighs 5000 pounds.

How FAST can I throw it? 

Is it (30000-5000)/10" like magnetics?  2500" per turn?
Is it (30000-5000)/100" like jumping?  250" per turn?

I can't find a direct rules passage. 

The rule you're looking for is in 8.4 (Throwing).  So:

30,000
- 5,000
______

25,000 / 10

2,500" (or about 2.4 miles)

Note that the number above (2,500") is just the distance it can be thrown, not the actual velocity.

Most targets are way under that (it's unlikely one could even see a target over two miles away), so for the most part you'll simply look on the Projectile Velocity chart (3.3) and go with the velocity there (based on how far it traveled that turn).  If the target was, say, 100" away, you'd add 1d8 damage.  It also seems to suggest that the maximum velocity anything could reach would be 1,000" per turn (for an extra 4d10).

Ironnerd, I agree that it's not very well stated.  It's all a little wonky, methinks.

I considered that part you underlined, but then it does say that it is used for "damage to the projectile".  So I figure the only times you'd need that would be figuring out how much damage Wolverine takes if he and Colossus are doing the "Fastball Special".

Using a more "realistic" range (one that an ordinary character could throw said truck, because as Ironnerd pointed out, no character is going to have the Agility to throw it 2+ miles), it might be thrown around 100" (that's probably farther than I've ever seen in my games).

With such a range, and assuming that one as a GM would rule that it is reasonable that the thrown truck would reach "maximum velocity" soon after being thrown, it would reach a rate/speed of 1,000" per turn.

So, after considering what Ironnerd said, I'd agree that you'd end up with a total of 2d8 (the weight of the truck from the Brawling Weapon table) +4d10 (velocity of 1,000").

If I'm throwing the truck at a villain who is standing 20" away, are we saying the truck speed can only reach 20" velocity?

I mean, I can throw a baseball faster than 20" at someone 100' away. 

If the hulk throws a truck, it's going to go pretty fast, even if you're only 100' away.

Any thrown object stops accelerating as soon as it leaves one's hand.

In Phrennzy's example, the truck would fly at 1,000 in/turn (or 227 mph) no matter how far away the target actually was (up to 2,500" of course).

Holy shit though, the rules state that damage to the projectile is figured as per falling.

Inches per turn times the square root of the objects basic hits.

So if the hulk picks me up and throws me 1000" per turn, I'll take 2000 points of damage when I hit the wall.  That's excessive to say the least, especially when the wall only takes 1d4+4d10. 

I am not using the falling rules for object damage.  That's obscene.

Just a thought... wouldn't the projectile and whatever it hits split the damage?

And that seems totally right to me as well.

So... even though I love what's in Revised edition, I allow for the fact that most of the information in the back of the book seems to have been hastily written... Just look at Saving Throws.

So what do you not like in Saving Throws?  Or do you just think it's too short?

I think that part if brilliant (we were just talking recently how strange it is that 5E D&D doesn't have an auto succeed if you save with a 20, or an auto failure with a 1).
