Question

Equation of motion of centre of mass numericals

Answer 1

Centre of Mass
Xcm =[M1*X1+M2*X2+............+Mn*Xn]/(M1+M2+.......Mn]

Ycm=[M1*Y1+M2*Y2+............+Mn*Yn]/(M1+M2+.......Mn]

Zcm=[M1*Z1+M2*Z2+............+Mn*Zn]/(M1+M2+.......Mn]


here M1,M2, Mn are masses
X1,X2 are distances of masses from Equilibrium position along X axis...
Similarly Y1,Y2 are along Y axis...and Z1, Z2...Zn are Zaxis...
Xcm is centre of Mass along X axis

Ycm is centre of Mass along Y axis

Zcm is centre of mass along Z Axis
