A rod of length 4 meters with density 6(x) = 2.1 +2.1x4grams/meter is positioned along the positive x-axis, with its left end at the origin. Find the total mass and the center of mass of the rod. Round your answers to four decimal places. The total mass of the rod is 438.48 grams. The center of mass of the rod is i meters. eTextbook and Media Hint Assistance Used The center of mass of an object lying along the x-axis between x = aand x = bis x(x) dx x = f(x) dx where 8(x) is the density (mass per unit length) of the object. Notice that the denominator is the total mass of the object.
