Solving Tension in Block System: Figure 5-57

[zenythz]

Homework Statement

Figure 5-57 (link above) shows three blocks attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table; the masses are mA = 6.80 kg, mB = 8.60 kg, and mC = 12.0 kg. When the blocks are released, what is the tension in the cord at the right?
