You set out to design a car that uses the energy stored in a flywheel consisting of a uniform 101-kg cylinder of radius r that has a maximum angular speed of 470 rev/s. the flywheel must deliver an average of 2.40 mj of energy for each kilometer of distance. find the smallest value of r for which the car can travel 300 km without the flywheel needing to be recharged.
