16. Two hoops, starting from rest, roll down identical inclined planes. The work done by nonconservative forces, such as air resistance, is zero (Wnc = 0 J). Both have the same mass M, but, as the drawing shows, one hoop has twice the radius of the other. The moment of inertia for each hoop is I = Mr, where r is its radius. Which hoop, if either, has the greater total kinetic energy (translational plus rotational) at the bottom of the incline? (a) The larger hoop (b) The smaller hoop (c) Both have the same total kinetic energy. Radius = R Mass = M Radius = R Mass - M
