Center of gravity between 2 points

Hello guys,

do you know about simple way how to calculate position of center of gravity between two points? For example first value has 10 kg and second 20 kg.

x = [1 3]
y = [2 5]
v = [10 20]
plot(x,y)
hold on
scatter(x,y,100,v,'filled')

axis([x(1)-1 x(2)+1 y(1)-1 y(2)+1])

x = [1 3];
y = [2 5];
v = [10 20];

xc = sum(v.*x)/sum(v);
yc = sum(v.*y)/sum(v);
