Can the center of mass of a two-object system be found as a weighted average (like the pencil problem)? In the physics simulation, set the mass of Ball 3 to 0 kg to remove it from the simulation, leaving only Balls 1 and 2. Set the mass of Ball 1 to 2 kg and the mass of Ball 2 to 4 kg to simulate the pencil problem. Test the prediction that the center of mass should be located at 6 m. Simulation ball color legend: Ball 1 = Red Ball 2 = Blue Ball 3 = Green Center of Mass = Purple
