Yes, my remark about t=0 was only in relation to part c.JulienB said:
For part b, the only other suggestion I have is that it should say to find αR in terms of m, L, k and x0.

SUMMARY
The discussion revolves around the dynamics of a pendulum influenced by a spring, specifically focusing on the equation of motion for small angles (α << 1). The equation derived is α'' + (k/m)⋅α = 0, leading to the angular frequency ω = √(3k/m) and the equilibrium angle αR = 2⋅B. Participants clarify the initial conditions and the role of gravity, ultimately arriving at the corrected equation of motion α'' + ((g/L) + (k/m))⋅α = 0, which incorporates gravitational effects. The conversation highlights the importance of accurately interpreting initial conditions and forces acting on the pendulum.
