41 In Fig. 10-27, two particles, each with mass m=0.85 kg, are fastened to each other, and to a rotation axis at O, by two thin rods, each with length d=5.6 cm and mass M=1.2 kg. The combination rotates around the rotation axis with the angular speed ω=0.30rad/s. Measured about O, what are the combination's (a) rotational inertia and (b) kinetic energy?
