I have been asked to come up with a formula by a rather persistent person who is Addiment that a wheel on an accelerating treadmill attached to a mass (such as a car) would not produce enough translational force to move the Car.
The Question as posed to that persons;
Please forgive any and ALL incorrect terminologies (I am not quite that educated, as you will probably guess )

We have a car with the bearings degreased and completely free of any imperfections such as bumps or imperfect roller bearings etc etc.
We have disconnected any drive train portions. (The cars engine is not running, it is not needed for this test, there is no drive being produced and delivered to the wheels by the cars engine, the wheels are free from any mechanical resistance friction from the diff etc etc.)
The wheels are Perfectly balanced.
To eliminate the rolling frictions from the question, try to imagine the wheels are as hard as steel. (Please also remove any friction from the bearings as a reason the car may move, IE Imagine frictionless)
For the purpose of the Example we will assume one more thing;
The Tyre and Treadmill traction is flawless.
NOW
What we are going to do is Start the belt and Accelerate the belt from 0mph to 200mph within 3 seconds while the car is sitting freely on top. (Belt direction is backwards car face forward, speedometer reads +mph not -mph ) after three seconds the Experiment is over and all data collected.
Here is the Question.
What will happen to the car?
(will it move during those three seconds? )
<relative to the Ground. Not relative to the treadmill surface>.
