It would be a better example to use a toy plane rather than a toy car. say the toy plane is held on the treadmill and the treadmill is accellerated. you holding the plane there is acting as thrust, all you have to do is push it forward with a little more thrust and it will move forward on the treadmill. at that point the treadmill will go faster, but because the thrust isnt coming from the wheels of the plane, it doesnt really matter. the wheels are just along for the ride. If the wheels were the ones driving the plane, it would matter becuase then there would be a ton of friction and it would never out run the treadmill. eventually the plane will get going fast enough to get air under the wings and take off.
very tricky question for a dumb person like me. Obviously it was cake walk for you edjumacated people.
