Three weights are attached to the corners of an equilateral triangle (side length 10 cm) made from stiff but very light wire. Measured from the bottom left corner, what is the center of mass of this object if M1 = 0.1 kg, M2 = 0.2 kg, and M3 = 0.3 kg?

• ah, I already took the course -

Please try the problems yourself before posting them all for us to do. If you get stuck we will help but we really do not need the practice of doing them all. You might well need the practice.
