When looking at the x2y2z2 to x1y1z1 transformation, the first ω is 3i rad/sec
When looking at the x1y1z1 to XYZ transformation, the second ω is 1k rad/sec

After the first transformation, aAx1y1z1  is -2.7j m/s

Use one generalized coordinate, x, which is the vertical displacement of the mass measured from the point where the spring is outstretched.  It is holonomic

unstretched ....

Stretched, h becomes h+x/2.  Is we defined a stretched length of the bottom of the triangle...the stretch of the spring as x moves downward. 

which can be rewritten in terms of l and x.
