A 3.0 kg mass is located at x=2.0 cm and y=4.0 cm.
A 3.0 kg mass is located at x= - 5.0 cm and y = 2.0 cm.
A 4.0 kg mass is located at x=3.0 cm and y= - 3.0 cm.
Where is the location of the center of mass??
please help thanks!

in the x-direction
x-center=(3*2-3*5+4*3)/10=3/10 cm
in the y-direction
y-center=(3*4+3*2-4*3)/10=6/10 cm

Center of mass=CM=x1m1+x2m2+x3m3/m1+m2+m3
=2 3-5 3 +3 4/3+3+4=6-15+12/10=3/10 cm
for x and y=4 3 +2 3 -3 4/10=12+6-12/10
y=6/10 cm,,...CM(0.3,0.6)..

x coordinate of CM will be
3*2+3*-5+4*3/3+3+4
=6-15+12/10
=6-3/10
=3/10
=.3
for y coordinate
3*4+3*2+4*-3/10
=12+6-12/10
=.6
so CM (0.3,0.6)
