Motive power for the experimental 10.1-Mg bus comes from the energy stored in a rotating flywheel which it carries. The flywheel has a mass of 1270 kg and a radius of gyration of 490 mm and is brought up to a maximum speed of 3750 rev/min. If the bus starts from rest and acquires a speed of 64 km/h at the top of a hill 106 m above the starting position, compute the reduced speed N of the flywheel. Assume that 11 percent of the energy taken from the flywheel is lost. Neglect the rotational energy of the wheels of the bus. The 10.1-Mg mass includes the flywheel. Answer: N = i rev/min
