Three 90.790.7 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)(0,0), mass B is at(10.2,19.5)(10.2,19.5), and mass C is at (17.3,13.4)(17.3,13.4).Find the xx- and yy‑coordinates of the center of mass of thetriangular object.
Two more 90.790.7 g masses are connected by a straight piece ofwire and affixed to the original configuration as shown. Thecoordinates of mass D are (0,−39.1)(0,−39.1) and the coordinates ofmass E are (0,39.1)(0,39.1). Find the xx- and yy‑coordinates of thenew center of mass of the combined object.
