What's the top speed on your car?

Assuming that the backpack didn't alter my aerodynamic profile then I would still be just as fast but not as long if I were unladen

Your analogy is correct if your are indicating it takes a certain amount of power to maintain a particular rate of acceleration.

Throw your buddy in the car with you and you'll still have the same terminal velocity although it will take you longer to get there, throw him on the roof, and not only will it take you longer to get there, but you will also slow down (unless screaming buddies have some aerodynamic enhancing property not known to modern science )
