Three identical popsicle sticks are arranged on an x-y coordinate system. One is placed on the x axis, with one end at the origin; one is placed on the y axis with one end on the origin; and one is placed parallel to the y axis, as shown. The length of each popsicle stick is 12.6 cm. (Neglect the finite width of the popsicle sticks and that they are rounded at the ends.)
(a) What is the x coordinate of the center of mass of the three sticks? answer in cm
(b) What is the y coordinate of the center of mass of the three sticks? answer in cm
