Think About It The center of mass of a solid of constant density is shown in the figure. In Exercises 43-46, make a conjecture about how the center of mass ( x ¯ , y ¯ , z ¯ ) will change for the nonconstant density ρ ( x , y , z ) . Explain. (Make your conjecture without performing any calculations.) ρ ( x , y , z ) = k z
Solution Summary: The author explains that the center of mass of a solid of constant density is (x,y,z)=kz.
