This video describes how to find a symbolic expression for the acceleration of the three-object system and the tension in one of the strings during acceleration. This three-object system is a more complicated version of a “modified Atwood's machine" that consists of a block or cart on a horizontal surface, connected with a string to a hanging mass over a pulley. The pulleys in this video are considered "ideal" (negligible mass and friction), so the tension in the string is the same on either side of the pulley. The first video linked below describes how to think through a traditional “modified Atwood's machine".
