It can be written in a more compact form as s 1 '7 s rCM W: mjrj. j= 1 Suppose you want to create a spaced themed decorative mobile for a child's room out of a 0.010 kg moon, a 0.020 kg planet, a 0.030 kg sun, and three massless rods of length 30.0 cm. You arrange them in an equilateral triangle and connect them to each other with the rods. You wish to hang the mobile from its center of mass so that it isn't crooked. If we place the origin at the sun, what is the x-coordinate (in m) of the center of mass? .10 x X Incorrect. Be sure that you use the correct X coordinates for each object. Remember that the sun is at the origin (0, 0). m If we keep the origin at the sun, what is the y-coordinate (in m) of the center of mass? 10 x x Incorrect. Be sure that you use the correct y coordinates for each object. Remember that the sun is at the origin (0, 0). m Say you hang some additional decorations onto the planet. Keep the origin at the sun. What will happen to the center of mass coordinates? O The X coordinate will increase the y coordinate will not change. 0 The X and y coordinates will both decrease. The x coordinate will increase and the y coordinate will decrease. \\/ J Correct. The center of mass will shift closer to the now heavier planet. This means the x coordinate will increase and the y coordinate will decrease
