I am new to Newtonian mechanics, and was wondering regarding the following:
The system pictured below is moving at acceleration $a$ towards the left. The mass of the ball is $m$, and there is no friction. If I take this as an non-inertial framework, I would analyse the situation as follows:
there is a force pressing the ball leftwards and a fictitious force "pushing backwards" at the wall. Of course gravity is pulling the ball downwards.
However, I was wondering what will happen to the normal force in such a scenario. Its y-component must of course be identical to $mg$, but what about its horizontal component, in light of the real force and the fictitious force to the right of it?
