Maximum acceleration of a dot on a slinky?

[uberifrit]

A dot (representing vibration) on a slinky exhibits simple harmonic motion as the longitudinal wave passes. The wave has an amplitude of 5,4 * 10^-3 m and a frquency of 4,0 Hz. Find the maximum acceleration of the dot.

Please could you explain what equations to use and how to answer in detail. This would be much appreciated as I am just starting this subject

Since you are studying simple harmonic motion, could you give the equation that describes the position of your dot along a straight line through time? The one that has sine in it?
