Simple Harmonic Motion Experiment Problem

[NP04]

Homework Statement

See Image. Part C only

Relevant Equations

Us = 1/2 kx^2
F = kx

I think you could try to solve for the forces based on when the spring falls from an incline at various angles theta, but I am not sure. Or spring potential energy? I'm really confused.

Is there any other method? Could it involve using water and wave harmonics? (We learned waves and sound in conjunction with this unit).

I am in AP Physics 1 and here is the course content we have learned so far (Not including Electrostatics + Circuits because I have minimal understanding of those and I doubt they have any relevance to the problem).

1: Kinematics
2: Dynamics
3: Circular Motion and Gravitation
4: Energy
5: Momentum
6: Simple Harmonic Motion
7: Torque and Rotational Motion
8: Mechanical Waves and Sound

Based on these topics we have covered in class, what other methods could be applicable to this problem?

Thanks in advance.

Your slope suggestion works by giving the spring some mechanical advantage over gravity, but friction could be a problem. How else can you provide mechanical advantage?

That stand looks suspiciously like a gallows. I can imagine question b being put in a much more gruesome way...
