Answer:
The maximum acceleration of the system is 359.970 centimeters per square second.
Explanation:
The motion of the mass-spring system is represented by the following formula:

Where:
 - Position of the mass with respect to the equilibrium position, measured in centimeters.
 - Position of the mass with respect to the equilibrium position, measured in centimeters.
 - Amplitude of the mass-spring system, measured in centimeters.
 - Amplitude of the mass-spring system, measured in centimeters. 
 - Angular frequency, measured in radians per second.
 - Angular frequency, measured in radians per second.
 - Time, measured in seconds.
 - Time, measured in seconds.
 - Phase, measured in radians.
 - Phase, measured in radians. 
The acceleration experimented by the mass is obtained by deriving the position equation twice:

Where the maximum acceleration of the system is represented by  .
.
The natural frequency of the mass-spring system is:

Where:
 - Spring constant, measured in newtons per meter.
 - Spring constant, measured in newtons per meter.
 - Mass, measured in kilograms.
 - Mass, measured in kilograms. 
If  and
 and  , the natural frequency is:
, the natural frequency is:


Lastly, the maximum acceleration of the system is:


The maximum acceleration of the system is 359.970 centimeters per square second.
