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 1.8 m diameter and a mass of 230 kg . its maximum angular velocity is 1500 rpm .a) a motor spins up the flywheel with a constant torque of 50 nm. how long does it take the flywheel to reach top speed? b) how much energy is stored in the flywheel?

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
