###### Problem 7 In the figure 1, two particles each with mass m = 0.85 kg, are fastened to each other; and to a rotation axis at 0, 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 0-0.30 rad/s. Measured about 0, what are the combination'$ (a) rotational inertia and (b) kinetic energy?
