Explanation / Answer

given data is masses m1=5kg,m2=3kg,m3=1.5kg

coordinates (x1,y1)=(6.5,8); (x2,y2)=(5,3);(x3,y3)=(4,1.5)

8.35 a)x-coordinateof center of mass Xcm=m1x1+m2x2+m3x3/(m1+m2+m3)

Xcm=5*6.5+3*5+1.5*1.5/(5+3+1.5)=5.63 m

8.35 b)y-coordinate of center ofmass Ycm=m1y1+m2y2+m3y3/(m1+m2+m3)

Ycm=5*8+3*3+1.5*1.5/(5+3+1.5)=5.39 m
