Find the center of mass of a rectangular block of width a and height b that has a nonuniform density such that when the rectangle is placed in the xy-plane with one corner at the origin and the block placed in the first quadrant with the two edges along the x- and y-axes, the density is given by σ(x, y) = σ0x, where σ0 is a constant. (Assume the width refers to the x-direction and the height refers to the y-direction. Use the following as necessary: a, b, and σ0.) x_cm=2a/3 what is y_cm? y_cm=?
