Chapter 09, Problem 51 A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provide a means for storing energy in the form of rotational kinetic energy and are being considered as a possible alternative to batteries in electric cars. The gasoline burned in a 111-mile trip in a typical midsize car produces about 1.52 x 10 of energy How fast would a 33.5-kg flywheel with a radus...
