In the design of a passenger bus, it is proposed to derive the motive power
from the energy stored in a flywheel. The flywheel, which has a moment of
inertia of 4.0 x 102 kgm2, is accelerated to its maximum rate of rotation of 3.0 x
103 revolutions per minute by electric motors at stations along the bus route.
a) Calculate the maximum kinetic energy that can be stored in the flywheel.
b) If, at an average speed of 36 kilometres per hour, the power required by the
bus is 20 kW, what will be the maximum possible distance between stations
on the level?
