A meter stick has constant thickness and width , but the material that the stick is constructed from is very strange ... it has a variable mass density that is given by, ρ(x) = 0.800(1 + 0.00250x) grams/cm3 where x is measured in cm. Find the center of mass of the meter stick, as measured from it's left end.
The problem shown asks for the center of mass of a meter stick with a variable mass density, the picture is the solution to the problem! where did this formula come from?!?!
The Attempt at a Solution
The hint says to use two simple integrals using the volume element dV=Adx
Can someone please help me understand where they got these 2 integrals from?
