Rotational energy of a segment is 0.102 JT.
What is rotational kinetic energy?
Similar to linear kinetic energy, the moment of inertia and angular velocity can be used to express the kinetic energy of a rotating object. The translational kinetic energy of the center of mass and the rotational kinetic energy about the center of mass add up to the total kinetic energy of an extended object.
Using rotational kinetic energy
We know,
KE = [tex]\frac{1}{2}[/tex]Iω²
Where,
I = Moment of Inertia
ω = Angular Velocity
Putting values in the equation,
KE = [tex]\frac{1}{2}[/tex](0.057)(1.90)²
KE = 0.102 JT
