6. The blocks shown in the figure are connected by flexible cable passing over frictionless pulleys. At 300-lb block, the coefficients of friction are Us=0.30 and Uk = 0.20 while at 200-lb block are Us=0.40 and Uk is 0.30. Compute the magnitude and direction of the friction force acting on each block.
