Here are the few equations i set up... which ultimately led to a wrong answer.

(In my solution, subscripts A refers to the ramp, B refers to the rolling pipe)

----------

I have a feeling that the acceleration if pipe A isn't simply downwards at 30deg.

Cos the ramp is rolling away, so the angle is relative to the ramp.

But I have no idea how to set up the required equations to correct this.

Any pointers?
