A set of weights were hung onto a meter stick where one of them has a mass of 100 g located right on the edge of the meter stick, another one with a mass of 80 g on the other edge, and another one with a mass of 150 g placed 15 cm from the 100 g weight. Find the center of mass of the meter stick with its hanging weights.
