Motive power for the experimental 17.0-Mg bus comes from the energy stored in a rotating flywheel which it carries. The flywheel has a mass of 1590 kg and a radius of gyration of 480 mm and is brought up to a maximum speed of 4490 rev/min. If the bus starts from rest and acquires a speed of 73 km/h at the top of a hill 122 m above the starting position, compute the reduced speed N of the flywheel. Assume that 8 percent of the energy taken from the flywheel is lost. Neglect the rotational energy of the wheels of the bus. The 17.0-Mg mass includes the flywheel. Answer: N= i rev/min
