Question

two bodies of masses 1kg nd 3kg are lying in xy plane at (0,0) and (2,-1) respectively what are the coordinates of the centre of mass

Answer 1

X(com)=(m1x1+m2x2)/(m1+m2)

X(com)=(3x2)/4

X(com)=6/4=>3/2

Y(com)=(m1y1+m2y2)/(m1+m2)

Y(com)=(3×-1)/4

Y(com)=-3/4

(X,y) of com = (3/2,-3/4)
