Unformatted text preview: are massless and frictionless. 9. Extra Credit Question Please work on this question by yourself! Magneto has tied up the X-Men in a diabolical ring of pulleys, as shown in the gure below. The ring is such that a single rope runs through all the pulleys, and the last ( N th) pulley is connected back to the rst pulley, as shown in the gure. Assume m 1 m 2 1 that all the pulleys and ropes are massless and frictionless. There are N pulleys and N X-Men, and all X-Men are of identical mass m (Colossus has been on a diet). Find the acceleration of the X-Men in this situation. m N-1 m N m 1 m 2 2...
