Three particles are attached to a thin rod of length 1.00 m and negligible mass that pivots about the origin in the xy plane. Particle 1 (mass 52 g) is attached a distance of 27 cm from the origin, particle 2 (35 g) is at 45 cm, and particle 3 (24 g) at 65 cm. (a) What is the rotational inertia of the assembly? (b) If the rod were instead pivoted about the center of mass of the assembly, what would be the rotational inertia?
