Find the kinetic energy of the flywheel after charging

Reference no: EM13500256

Some European trucks run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 200p rad/s. One such flywheel is a solid, uniform cylinder with a mass of 600 kg and a radius of 1.2 m.

(a) What is the kinetic energy of the flywheel after charging?

__________J

(b) If the truck operates with an average power requirement of 8.0 kW, for how many minutes can it operate between chargings?

__________min
