    Answer:

    white, blue and red

    Explanation:

    Force is given by

    [tex]F=ma[/tex]

    where

    m = Mass of object

    a = Acceleration of the object

    If the acceleration is same for all the cars the force needed to be applied will depend on the mass of the car. The heaviest car requiring the most force and the lightest car requiring the least amount of force.

    Here, the weight of the cars in descending order is white, blue and red.

    So, the cars in order from the most to least amount of force needed to move them is white, blue and red.
