Chapter 10, Problem 63(choose chapter or problem)
As an automotive engineer, youre charged with improving the fuel economy of your companys vehicles. You realize that the rotational kinetic energy of a cars wheels is a significant factor in fuel consumption, and you set out to lower it. For a typical car, the wheels rotational energy is 40% of their translational kinetic energy. You propose a redesigned wheel with the same radius but 10% lower rotational inertia and 20% less mass. What do you report for the decrease in the wheels total kinetic energy at a given speed?
