## Homework Statement

I have 2 boxes A and B and they have a mass of 1kg and 2kg respectively. They are pushed with a force of 10N and 20N horizontally but B has twice the surface area as A. Which object would come to a constant velocity first and which constant velocity would be lower?

## Homework Equations

F=ma

## The Attempt at a Solution

I'm not sure how to answer this because usually for these questions I'm only given one object to access. Now with 2 objects, i know that B would have twice the resistive force for any specific velocity. So now that I'm pushing them, I'm not sure how the air resistance would change for the 2 boxes.

Because now velocity and surface area both affects the air resistance experienced by the boxes. So for sure B has a greater surface area and both have an increasing velocity. However, I'm not sure whether which box would have a greater or smaller air resistance because the velocity which is affected by the air resistance is affected by velocity and surface area. So now I'm really confused about this whole question. Can someone enlighten me? Thanks :)
