Question

Four objects are situated along the y axis as follows: a 2.00 kg object is at +3.00 m, a 3.00-kg object is at +2.50 m, a 2.50-kg object is at the origin, and a 4.00-kg object is at -0.500 m. Where is the center of mass of these objects?

Answer 1

2.00*(y-3.00) + 3.00(y-2.50) + 2.50(y-0.0) + 4.00(y+0.50) = 0
y = 1.00

Answer 2

answer

Answer 3

Ycm= (2×3)+(3×2.5)+(2.5×0)+(4×-0.5)/2+3+2.5+4
Ycm=1
