ok. so i must be missing something fundamental. yesterday i finally found an answer of .1 for the coefficient of kinetic f. but now, isolating block b with friction pulling to the left and horizontal tension as a force on the right i am getting some odd answers that cannot fit a coefficient. ie...

Homework Statement Block A of mass 2M hangs from a cord that passes over a pulley and is connected to block B of mass 3M that is free to move on a frictionless horizontal surface. The pulley is a disk with frictionless bearings, having a radius R and moment of inertia 3MR^2. Block C if mass...
