As we are in our second independent unit, I thought I little review picture couldn't hurt. Remember:

1.) Max acceleration is achieved when the spring is at -amplitude or +amplitude.

2.) Max velocity is achieved at equilibrium.

And, along with this, we must know:

KE= (1/2)kA2sin2(wt) w= angular frequency, k= spring constant, A= amplitude, t= time

PE= (1/2)kA2cos2(wt)

These equations are useful when finding the Potential or Kinetic Energy at time, t, in the oscillation.
