That's not solving physics. Physics is not a problem, it's a branch of the natural sciences. We can solve physics-related problems, but it's not like if we've solved enough physics-related problems we have solved physics.
You consider the problem of having your mug at a convenient height and distance from your sitting positing to be solved, but not the coffee table itself.
