SUMMARY
The moment of inertia of a flywheel can be calculated using the equation ½Iω² = 22.0 kJ, where ω is the angular speed in radians per second. In this case, the angular speed of 14.5 revolutions per second converts to approximately 91.1 radians per second. Substituting these values into the equation yields a moment of inertia of 0.00531 kg·m². This calculation emphasizes the importance of unit conversion in physics problems.
