Question: 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 1.5m diameter and a mass of 220 kg. Its maximum angular velocity is 1400 rmp

A motor spins up the flywheel with a constant torque of 51 Nm

1. How long does it take the flywheel to reach top speed? in s

2. How much energy is stored in the flywheel? in J

The flywheel is disconnected from the motor and connected to a machine to which it will deliver energy. Half the energy stored in the flywheel is delivered in 2.1s

3. What is the average power delivered to the machine? in W

4. How much torque does the flywheel exert on the machine? Nm

Answer these questions and show each and every step with example.
