In this derivation (see attached image), does the author assume that the rope doesn't slip? Because if it does, then there is no guarantee that ##\ddot{l} = 0##, right?
Also, does this equation apply to all pulley systems where one pulley is fixed and the other is allowed to move? For example, would this equation still hold for an arrangement where ##|h| > |X|##?
Also, would this equation hold if we were to choose a coordinate system where ##x## and ##X## are both negative?
