Three blocks are located on a horizontal table. The coefficient of kinetic friction between the blocks and the table is 0.069. They are connected by a massless cord, as shown in the figure below, and pulled to the right. The masses of the three blocks are m1 = 8.5 kg, m2 = 3.0 kg, and m3 = 7.5 kg. The pulling force is equal to T3 = 80.0 N. What is the tension T2?

Why the answer is c?
In the figure below, all surfaces experience friction. An external force is exerted on B and all the blocks are accelerating to the right with the same acceleration. Is the magnitude of the horizontal component of the force exerted by A on B greater than, equal to, or less than the magnitude of the horizontal force exerted by A on C? Equal to Less than Greater than Unable to determine without knowing the mass of...
