Some European trucks run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of
250 Trad/s. One such flywheel is a solid, uniform cylinder with a mass of 730 kg and a radius of 0.972 m. (a) What is the kinetic energy
of the flywheel after charging? (b) If the truck uses an average power of 7.8 kW, for how many minutes can it operate between
chargings?

A cyclist intends to cycle up a 8 degrees hill whose vertical height is 175 m. If each complete
revolution of the pedals moves the bike 5.5 m along its path, calculate the average force that must
be exerted on the pedals tangent to their circular path. Neglect work done by friction and other
losses. The pedals turn in a circle of diameter 30 cm. The total mass of the cyclist and their bike is
110 kg.
