I figured it out

Well, I haven't exactly found an acceleration, however I imagine it is going to something related to F=ma and the mass will cancel somewhere through substitution and algebra. I just can't figure out where to start.

Homework Statement The amplitude of the oscillation gradually increases till block B starts to slip. At what A does this happen?(there is no friction between the large block and the surface) Homework Equations Force equations etc... (F=ma) and I reckon it has something to do...

Heya, I have this exact same problem. I played around a bit. Recall "The quantity (wt + φ) is called the phase, and is measured in radians. The cosine function traces out one complete cycle when the phase changes by 2p radians. The phase is not a physical angle!" So, by that and the graph, all...
