let the density of the objects is p
let the x coordinate the center of mass is x
x = (m1 * x1 + m2 * x2 + m3 * x3)/(m1 + m2 + m3)
x = (p * pi * (25.6/2)^2 * (25.6/2) + p *pi * (15.8/2)^2 * (15.8/2) + p * (9.6/2)^2 * 9.6/2))/(p * pi * (25.6/2)^2 + p *pi * (15.8/2)^2 + p * (9.6/2)^2 )
x = ( pi * (25.6/2)^2 * (25.6/2) + pi * (15.8/2)^2 * (15.8/2) + (9.6/2)^2 * 9.6/2))/(pi * (25.6/2)^2 + *pi * (15.8/2)^2 + (9.6/2)^2 )
x = 11.23 cm
the x coordinate of the center of mass is 11.23 cm

3. This problem revisits the question from Problem Set I about finding the dimensions of a one-liter can that will have the minimum cost. We will now approach it using calculus methods. In class, we found the dimensions of a right circular cylinder (a “can") that has a volume of 1,000 cm3 using the minimum possible material. This assignment changes that problem slightly by seeking the minimum cost for a right circular cylinder whose volume is 1,000 cm3 where the...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
