A bus is designed to draw its power from a rotating flywheel that is brought up to its maximum rate of rotation (3060 rev/min) by an electric motor. The flywheel is a solid cylinder with a mass of 1060 kg and diameter 0.96 m. If the bus requires an average power of 9.4 kW, how long does the flywheel rotate

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

Motion i think. hope it

I’m not sure about this question
