SUMMARY
This discussion focuses on the concepts of work and energy, specifically addressing kinetic energy, gravitational potential energy, and spring potential energy in a physics problem involving a block and a spring. Participants clarify that the problem assumes no frictional forces, allowing for a direct conversion of gravitational potential energy to kinetic energy and subsequently to spring potential energy. The formula for spring compression, F=kx, is highlighted as essential for solving the problem, emphasizing the need to resolve forces accurately.

I need some help to help you. Would you mind posting some of the ideas that come to your mind in how to solve this. There are three types of energy in this problem: kinetic, gravitation potential, and spring potential. Which do you think are relevant? Where are the possible places that the energy can be?

I meaning kinetic energy and spring potential
The cube is to striking down the spring

Has the question specified that there is no frictional force or drag forces? That is, is all gravitational potential energy being converted to kinetic and all kinetic being converted to spring potential?

yes I believe that is what he means. What I meant to say is that do you see a role for kinetic energy in this question?Serac said:
Initially, it is evaluated when the block is at rest. It then asks to find the maximum compression; when the block is also at rest.

No, I don't see a role for Kinetic energy, I was just going through the steps.
If you mean how much force it would be if it was just placed onto the spring, at that angle, then it would be weight of the object, in the horizontal direction. So, you would have to resolve the forces, then solve as a usual spring compression: F=kx.
If we are talking about letting it lose, then calculating it, it would be the change in gravitational potential is equal to the elastic potential energy acting on the spring, as it is all converted.
