A flywheel is a solid disk that rotates about an axis that isperpendicular to the disk at its center. Rotating flywheels providea means for storing energy in the form of rotational kinetic energyand are being considered as a possible alternative to batteries inelectric cars. The gasoline burned in a 491-mile trip in a typicalmidsize car produces about 4.36 x 109 J of energy. How fast would a39.1-kg flywheel with a radius of 0.316 m have to rotate to storethis much energy? Give your answer in rev/min.
