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 1200[rpm] A motor spins up the flywheel with a constant torque of 50 [N*m]. How long does it take the flywheel to reach top speed?
