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 1.5 m diameter and a mass of 250 kg. its maximum angular velocity is 12000 rpm. a motor spins up the flywheel with a constant torque of 50 nm. how long does it take the flywheel to reach top speed?
