1. Let's put a ball in an empty space with a mass of 280 kg and a radius of 6 meters. Imagine that there is a elastic material that obey's Hooke's Law around this ball. The initial radial extent of the material is 2 meters.
i'm looking for K. But i don't know how to define the force.

Elasticity problems in 3 dimensions are treated via tensors, you cannot reduce them to a scalar, as in Hooke's simplistic approach.

3. The force has direction and magnitude.

Do you even read my explanations?

5. Yes i did! I'm just wondering how i can represent this problem vie tensors i'm still in highschool. I have read about them. But i'm new and i don't understand them well.If you help that would be great.

Start learning here.
