A mass resting on a horizontal, frictionless surface is attached to one end of a spring, the other end is fixed to a wall. It takes 3.6 J of work to compress the spring by 0.13 m. If the spring is compressed, and the mass is released from rest, it experiences a maximum acceleration of 12 m/s² Find the value of the spring constant. Express your answer to two significant figures and include the appropriate units. HÅ P k= Value Units Submit Request Answer Part B Find the value of the mass.
