A mass sitting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. 3.2 Joule of work is required to compress the spring by 0.12 meter. If the mass is released from rest with the spring compressed 0.12 meter, it experiences a maximum acceleration of 18 m/s2. Determine what the value of the mass.
