PLZ HELP!! I am puzzled with this problem, and all i could find are that the forces equal, but the ans int eh back of the textbook clearly says the solution is 0.2 m/s2 Question: This situation occurs in a pulley system. A 80.0 kg man inside a 40.0 kg dumb waiter (like an elevator) pulls down on the rope. At the end of the rope, it is attached to the dumb-waiter. At the other end, the person exerts a force. At that moment, the scale on which he is standing reads 200N. Determine the elevator's acceleration. THX for ur time!!
