How Do You Solve the Block and Spring Dynamics Problem?

[fireemblem13]

One of three blocks is attached to ceiling by a cord. Two others are connected by springs to the first block and to each other with coefficient k. What's the deformation of the springs? What's the tension in the cord? If the cord is cut, what's the acceleration of the blocks?

I'm somewhat clueless, so I'd appreciate a nudge in the right direction.

Start with free body diagrams for each block, then use Hooke's law to find the deformation in the springs (and the fact that the blocks are in static equilibrium, so F_net=0)
