Haste and Horses

[The Persian]

Would you say that casting Haste on a pair of horses that pull a carriage make the carriage move faster, or is that STR dependent?

 

[shilsen]

I'd say it would increase the carriage's speed.

Haste would make the horses faster.

 

[The Persian]

Haste would make the horses faster.

I figured as much, just wondered if they needed to be stronger to speed up the carriage's progress in making it easier to pull.

Actually, it would be up to the DM. Carriages don't have thier speed listed, and the closest thing to one is the cart/wagon speed of 2 miles per hour/16 per day far, less than even the slowest mounts.

The listed vehicles have thier own speeds, they don't just use the speed of the mounts pulling them.

F=m*a

Tha amount of force applied to the carriage is increased by the increased acceleration rate of the hasted horse. From a rules perspective, yes it should affect the rate. The maximum speed of the carriage should be based upon the speed of the mount, adjusted for the encumbrance gained by the weight of the carriage and passengers.

No, definitely not. The 'a' in your equation must be with respect to the carriage, not the horse. If you want to increase the 'a' of the carriage, and the mass remains constant, the horse must increase its applied force on the carriage. Merely increasing the horse's potential 'a' (actually, it's speed we're talking about, not acceleration, so that's another error you're ignoring) has nothing at all to do with this equation, unless you mean to propose that by increasing the potential speed of the horse, then the horse can increases its maximum Force upon the carriage, and furthermore that the carriage can sustain that increased force without breaking apart. This last part is key because apparently per the RAW, carriages have a maximum speed regardless of who/what's pulling it.
