The question has been screenshotted, along with the given diagram. Basic stuff I know, but I can't seem to get my head around pulley systems. T
F(net) = m ⋅ a(system)
The Attempt at a Solution
I understand the rope to be considered inextensible. Also, I understand that the tension must equal the weight of the man & chair, but beyond that I don't know how to break it down.
I labelled a reference frame with x being positive down.
