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 309-mile trip in a typical midsize car produces about 2.96 x 109 J of energy. How fast would a 10.1-kg flywheel with a radius of 0.437 m have to rotate to store this much energy? Give your answer in rev/min.
