The cable AB keeps the 8-kg collar A in place on the smooth bar CD. The y axis points upward. Determine the distance s from C to the collar A for which the tension in the cable is 150N.
B: (0m, 0.5m, 0.15m)
C: (0.4m, 0.3m, 0m)
D: (0.2m, 0m, 0.25m)
collar A's location is unknown. The required is the distance between C and collar A. The answer is 0.305m, but I need the solution for it.

Someone answered this in yahoo answers. Can someone verify it?

s=distance between A and C
The Attempt at a Solution
I'm not sure about this part...
I equated the "s" in the previous part and got...
After that, my solutions just go in circles. I couldn't get what Ax is.
Also, Is my use of Ax, Ay, Az correct? I'm doubting about it.
