Two point particles, A and B, with masses 4 kg and 6 kg, respectively, are connected by a rigid massless rod with a length of 0.6 m. The entire system is able to freely rotate, but is initially at rest. The following net torque acts on the system:

T(net) (t)= (2 Nm/s)t

What is the work (in J) done by this torque for during the first 2 s it acts on the particles?
