Problem 1b. A rotating object. (1 point) An object is made of a thin rod with mass m = 0.250 kg and length 2a (a = 0.300 m) on the y-axis and half of a thin hoop with mass M = 0.200 kg and radius a attached to the end points of the rod as shown. The object is located completely within the xy-plane. The +z-axis is perpendicular to the drawing through O. The dashed line is the line y = x in the x)- plane. This is the axis of rotation of the object in this problem. Calculate the moment of inertia of the object about the y-axis. Enter the moment of inertia in kg m2
