Question

What will be the centre of mass, if objects A,B,C lies along the x­axis where:­

A= 3 kg at +2 m 

B= 4 kg at +1.5 m 

C= 3.5 kg at origin​

Answer 1

Answer:

centre of mass=M1X1+M2X2+M3X3

______________________

M1+M2+M3

centre of mass=3*2+4*1.5+3.5*0/3+4+3.5

centre of mass =6+6+0/10.5

centre not mass=12/10.5=1.14

Answer 2

Answer:

so the centre of mass lies at a distance of 1.142 m from the origin along the positive x-axis
