3) A 600N block is lifted by the friction free pulley system shown. a) How many strands of rope support (are attached to) the 600N weight? b) What is the tension in each strand? c) What is the tension in the end held by the man (and thus the force he is applying)? d) If the man pulls his end down 120 cm, how much work has he done on the weight?
