Is this problem neglecting air friction and mass of the rope? Also, what's pulling that rope?confusedaboutphysics said:

I think what Kazza is saying is [itex]\vec{F_T} - mg = m\vec{a}[/itex]. If that's correct then you can think of a free body diagram of the rope with the upward force equal to ma, and the downward force equal to mg. But don't take my word on it
