1. The coordinates of the center of mass for the extended object shown in the figure are (L/4, −L/5). What are the coordinates of m1? (Assume m1 = 7 kg, m2 = 3 kg, and m3 = 5 kg. Use any variable or symbol stated above as necessary.) 2. 3. I too the centroid cordinates and substracted them from each corresponding x and y value in each coordinate. Then, distributed the mass to each corresponding coordinate...ie 7(x,y) = (7x,7y), then solved for x and y. My answer was (L/7, -21L/10). But its wrong. Anybody have any insight?
