16. A 0.40 m rod has non-uniform linear mass density given by (r) = Ar, where 'r' is the distance from the end of the rod to a point on the rod and the coefficient A has a numerical value of 2.00. What is the mass of the rod? What is the center of mass of the rod? What is the moment of inertia of the rod if the axis of rotation is perpendicular to the rod and at the end of lower density? What is the moment of inertia of the rod if the axis of rotation is perpendicular to the rod located at the center of mass?
