Thermodynamics problem - weight and piston connected by string

[Chestermiller]

I have used the same values given in the problem, what is wrong with my calculations?

As I said in my previous edited posting, I redid my calculations, and obtained 0.178 m for the equilibrium position and 1.27 m/s for the velocity. This velocity agrees with your value.

Ah, then the given answer must be wrong.

Thanks for the help voko, Chestermiller and DrClaude!
