Assuming the pick-up trucks, trailers and road conditions are exactly the same, which vehicle will take a longer distance to stop?

I’ve answered this before so I know the question is missing an important given and that given is: 1 has an empty trailer and the other has a fully loaded one. 

So, it would be the fully loaded trailer that would take a longer distance to stop because a lot of weight is being pulled, and when the brakes are started, the fully loaded trailer is more like pushing against the truck.

this could be newton#'s law of cooling. the cooling curve is exponential

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
