A.) What is the x-coordinate of the center of mass?
B.) What is the y-coordinate of the center of mass?

## General guidance

Concepts and reason

The concept required to solve this problem is center of mass. Use the equation for the x-component of the center of mass and calculate the x-component of the center of mass of the given system. Use the equation for the y-component of the center of mass and calculate the y-component of the center of mass of the given system.

Fundamentals

The x-coordinates of the center of mass of the given system is,

Here, is the x-coordinate of center of mass, is the mass of particle, and is the x-coordinate of particle.

The y-coordinates of the center of mass of the given system is,

Here, is the y-coordinate of center of mass and is the y-coordinate of particle.
