Thomas helps his older brothers, who own a junk yard, on the weekends to earn extra money. He likes to help them push broken-down cars to the back of the junk yard because it makes him feel strong.

Answer:

white, blue and red

Step-by-step explanation:

Force is given by


F=ma

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.
