You release the object, what is the period of oscillation of the mass/spring system?  Using yt=Acos(wt), what is the expression of the vertical motion along the y-axis?  What is the maximum speed of the oscillating object? What is the maximum kinetic energy? Do these values make sense from the values in part b?
