Four small 0.200 kg spheres, each of which you can regard as apoint mass, are arranged in asquare 0.400 m on a side and connected by light rods.
A 0.400 m 0.200 kg B (a) Find the moment of inertia of the system about an axis along the line CD. (b) The system starts to rotate from rest in the counterclockwise direction with an angular acceleration of + 2 rad/s². What is the angular velocity of the system after rotating 3 revolutions? (c) Calculate the rotational kinetic energy of the system. (KE-½Iw₂) (d) Calculate the angular momentum of the system. (L=Iw) (e) If the masses of spheres on the upper left and lower right were doubled, how would it affect your responses to (a) and (b) ?
