Motive power for the experimental 15.7-mg bus comes from the energy stored in a rotating flywheel which it carries. the flywheel has a mass of 1510 kg and a radius of gyration of 445 mm and is brought up to a maximum speed of 4450 rev/min. if the bus starts from rest and acquires a speed of 61 km/h at the top of a hill 110 m above the starting position, compute the reduced speed n of the flywheel. assume that 9 percent of the energy taken from the flywheel is lost. neglect the rotational energy of the wheels of the bus. the 15.7-mg mass includes the flywheel.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
