There is friction between the block and the table. The suspended 4 kg mass on the left is moving up, the 2 kg mass slides to the right on the table, and the suspended mass 7 kg on the right is moving down. The acceleration of gravity is 9.8 m/s/s. What is the magnitude of the acceleration of the system? Answer in units of m/s/s. (the picture wont work) the µ = 0.16.
