Two identical springs with spring constant k and with two Identical masses m

[big_zipp]

I am trying to figure out what the kinetic and potential energy of this system. A spring is attached to point A, a mass m hangs from the other end of the spring. Another spring hangs from the first mass, and another mass hangs from the second spring. There is no motion in the horizontal direction. The non stretched spring's length is b.

I'm just looking to find the kinetic and potential energy.

Thank you

What are your thoughts? What are the Relevant Equations? Why would there be kinetic energy involved -- it sounds like the system is in motionless equilibrium?
