To drive a typical car at 40 mph on a level road for one hour requires about 3.2 × 107 j of energy. suppose we tried to store this much energy in a spinning, solid, uniform, cylindrical flywheel. a large flywheel cannot be spun too fast or it will fracture. if we used a flywheel of diameter 1.2 m and mass 400 kg, what angular speed would be required to store 3.2 × 107 j?
