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 458-mile trip in a typical midsize car produces about 1.32 x 109 J of energy. How fast would a 35.9-kg flywheel with a radius of 0.293 m have to rotate to store this much energy
