The center of mass is located 2.5 m from 3 kg point mass, (and 1.5 m from the 5 kg point mass) on X-axis. This result shows that the center of mass is located closer to larger mass. If the origin is shifted to the center of mass, then the principle of moments holds good. m1x1=m2x2; 3x2.5=5x1.5;7.5=7.5.
Calculate the center of mass of a given system. Apply the center of mass concept in two and three dimensions. Calculate the velocity and acceleration of the center of mass.

Explain the meaning and usefulness of the concept of center of mass. Calculate the center of mass of a given system. Apply the center of mass concept in two and three dimensions. Calculate the velocity and acceleration of the center of mass.
Center of mass solved problems. Question 1 Find the center of mass of a uniform semi-circular ring of radius R and mass M. Solution: Let us consider the center of the ring as origin. We would have to solve this problem using calculus method.
The \(y\) position of the center of mass is given by: \[\begin{aligned} y_{CM} = \frac{1}{M}\int y dm\end{aligned}\] where \(M\) is the total mass of the wire.
In the previous modules on “Center of Mass and Translational Motion,” we learned why the concept of center of mass (COM) helps solving mechanics problems involving a rigid body. Here, we will study the rigorous definition of COM and how to determine the location of it.
