The four particles shown below are connected by rigid rods of negligible mass where y, = 6.30 m. The origin is at the center of the rectangie. The system rotates in the xy plane about the z axis with an angular speed of 5.50 rad/s. 3.00 kg 2.00 kg 2.00 kgO 4.00 kg +4.00 m (a) Calculate the moment of inertia of the system about the z axis. kg- m2 (b) Calculate the rotational kinetic energy of the system.
