Delivery trucks that operate by making use of energy stored in a rotating flywheel have been used in Europe. The trucks are charged by using an electric motor to get the flywheel up to its top speed of 202-? rad/s. One such flywheel is a solid, homogeneous cylinder with a mass of 550 kg and a radius of 1.0 m. What is the kinetic energy of the flywheel after charging? If the truck operates with an average power requirement of 7.0kW, for how many minutes can it operate between chargings?
