I’m currently finding a library for visualization of force distribution between 2D objects.

Example,  
Below is an image of 3 boxes on a trolley.  
When the trolley is accelerating to the right, how will the force act from the middle big box on the left smaller box be distributed?

I’m currently using Box2d library. Is there any way to visualize the force between objects?
