To solve this problem we will use the concepts given by the rotational kinetic energy which describes the energy in a body product of its moment of inertia and its angular velocity, mathematically this is given as,
[tex]KE = \frac{1}{2} I\omega^2[/tex]
Where,
I = Moment of Inertia
[tex]\omega[/tex]= Angular Velocity
Replacing with our values we have that,
[tex]KE = \frac{1}{2} (0.57)(25)^2[/tex]
[tex]KE = 178.125J T[/tex]
Therefore the rotational energy is 178.125J
