6. A mass sitting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. 3.6 J of work is required to compress the spring by 0.1 m. If the mass is released from rest with the spring compressed 0.1 m, it experiences a maximum acceleration of 12 m/s2. Find the value of the mass.
