A mass sitting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. 5.5 J of work is required to compressed the spring by 0.16 m. If the mass is released from rest with the spring compressed, it experiences a maximum acceleration of 27 m/s2. Find the spring constant? what is the mass?
