A system of point particles is shown in the following figure. Each particle has mass 0.3 kg and they all lie in the same plane. a. What is the moment of inertia of the system about the given axis (imagine the axis is out of the page)? b. If the system rotates at 5 rev/s, what is its rotational kinetic energy? 40 cm axis 20 cm 60 cm
