Three masses are connected by massless rigid rods. Rods AC and CB have length l= 16.6 cm. If massA=115.0 g, massB=206.0 g, and massC=310.0 g, what are the coordinates of the center of mass? (Enter your answer for the x coordinate first, followed by the y coordinate.)
draw the picure. Write coordinates for all the masses (use trig, if necessary).
If you have questions then, repost.
