Physics oscillations?

A 35.0 kg block at rest on a horizontal frictionless table is connected to the wall via a spring with a spring constant k= 29.0 N/m. A 2.00E-2 kg bullet travelling with a speed of 5.300E+2 m/s embeds itself in the block. What is the amplitude of the resulting simple harmonic motion? Recall that the amplitude is the maximum displacement from equilibrium.
