our objects are situated along the y axis as follows: a 1.94 kg object is at +3.27 m, a 2.76 kg object is at +2.18 m, a 2.78 kg object is at the origin, and a 3.99 kg object is at -0.360 m. Where is the center of gravity of this system?

Answer 1

Add the four mass x position products and divide by the total mass.
[1.94*3.27 + 2.76*2.18 + 2.78*0 - 3.99*0.360]/11.47 = ___ m
