if it takes a 4 door sedan x amount of feet to go from 65 mph to 45 mph (and i don't know how many feet that is) on a dry straight road, how many feet would it take for a large Mack truck transporting a full load of fluid, which would be most likely twice as heavy, to slow down from 65 to 45? Also, as the truck slows, it is moving to the right. Because of the fluid in the tank pushing forward and to the right also, would this have an effect on how well the truck can travel straight or would it naturally pull to the right side?
