A system of point particles is shown in the following figure. Each particle has mass 0.43 kg, and they all lie in the same plane. 62 cm 49 cm axis 29 cm (a) What is the moment of inertia (in kg. m²) of the system about the given axis? kg-m² (b) If the system rotates at 5.6 rev/s, what is its rotational kinetic energy (in J)?
