Temperature is the average kinetic energy of an object
        
             
        
        
        
Answer:
The center of mass for the object is   from the origin
 from the origin 
Explanation:
From the question we are told that 
    The mass of the first object is  
    The position of first object with respect to origin 
    The mass of the second object is  
    The position of second object with respect to origin 
    The mass of the third object is  
    The position of third object with respect to origin 
    The mass of the fourth object is  
    The position of fourth object with respect to origin 
Generally the center of mass of the object along the x-axis is  zero  because all the mass lie on the y axis 
Generally the location of the center mass of the object is mathematically represented as
