Flywheels are large, massive wheels used to store energy. They can be spun up slowly, then the wheel's energy can be released quickly to accomplish a task that demands high power. An industrial flywheel has a 1.7 m diameter and a mass of 275 kg. A motor spins up the flywheel with a constant torque of 45 N m. How long does it take the flywheel to reach top angular speed of 1150 rpm?
