Physics

Three 81.6 g masses are connected in a triangular shape bymassless rigid wires as shown in the first image (which is notdrawn to scale). The coordinates of each mass are given incentimeters. Mass A is located at (0,0) , mass B is at (12.2,22.5), and mass C is at (21.3,13.4) . Find the ? - and ? ‑coordinates ofthe center of mass of the triangular object. A graph has a verticalY axis and a horizontal X axis. Three masses are shown. Mass A islocated at (0,0), mass B is at (12.2,22.5), and mass C is at(21.3,13.4). ?cm= cm ?cm= cm Two more 81.6 g masses are connectedby a straight piece of wire and affixed to the originalconfiguration as shown. The coordinates of mass D are (0,−27.0) andthe coordinates of mass E are (0,27.0) . Find the ? - and ?‑coordinates of the new center of mass of the combined object. Agraph has a vertical Y axis and a horizontal X axis. Five massesare shown. Mass A is located at (0,0), mass B is at (12.2,22.5),mass C is at (21.3,13.4), mass D is at (0, -27.0), and mass E is at(0, 27.0). ?cm= cm ?cm= cm
