SUMMARY
The discussion focuses on calculating the center of mass velocity for a system of two 30 kg masses with given velocities v1 = 14i - 18j and v2 = -28i + 14j. The solution involves applying the principle of conservation of momentum. By summing the momenta of both masses and dividing by the total mass, the center of mass velocity is determined to be v_cm = (-7i - 2j) m/s.
