G) if the angular acceleration of a rigid body is zero, what is the functional form of the angular velocity? b) what if another planet the same size as earth were put into orbit around the sun along with earth. would the moment of inertia of the system increase, decrease, or stay the same? c) does increasing the number of blades on a propeller increase or decrease its moment of inertia, and why? d) can you think of a body that has the same moment of inertia for all possible axes? if so, give an example, and if not, explain why this is not possible. can you think of a body that has the same moment of inertia for all axes passing through a certain point? if so, give an example and indicate where the point is located. e) to maximize the moment of inertia of a flywheel while minimizing its weight, what shape and distribution of mass should it have? explain. f) is it possible to change the (translational) kinetic energy of an object without changing its rotational kinetic energy? what about the reverse of it?
