The resultant force is nonzero in the y direction so you can't balance the forces in a triangle.
Resolve the forces in x and y directions. What must happen in the x direction?

Sort of. The net force in the x direction should be 0.

But I’m confused as to why that should be 0 if it’s not in equilibrium and that the y direction shouldn’t be equal?

So it can be in equilibrium in the x direction, but have a non-stop resultant force (not in equilibrium) in the y direction.

Forces in orthogonal directions (90 degrees to each other) are independent.
So it can be in equilibrium in the x direction, but have a non-stop resultant force (not in equilibrium) in the y direction.

So to have a resultant force, the equilibrium isn’t equal? And if x is (for instance) is not in equilibrium do I automatically assume that y would be in equilibrium?

* The resultant force in the x direction is zero.
* The resultant force in the y direction is non-zero

The question tells you that the resultant force is in the y direction, so
* The resultant force in the x direction is zero.
* The resultant force in the y direction is non-zero

Ahhhhhh trying to get me head around mechanics, I got you now tho thanks!! Finally made sense

The vertical (ball) motion does not affect the horizontal (ball) speed.

Spot the independent ball motion towards the end

If it’s large scale enough friction would affect it wouldn’t it
