Final answer:
The configuration of the masses on a surface with friction depends on the specifics of the physics experiment or theoretical setup, with various possible arrangements like connected carts or blocks used for collisions or force analysis.
Step-by-step explanation:
The configuration of the masses connected on a surface with friction is not explicitly stated in the options provided. To determine the configuration relevant to a physics problem, one would typically consider the specific experiment or theoretical setup in question. For example, when analyzing collisions or forces in physics, masses could be arranged in different ways depending on the experiment, like masses on a cart track or blocks connected by a massless rope. To analyze forces on connected masses, separate free-body diagrams for each mass would be drawn to apply Newton's second law of motion and ascertain their movement.
