When moment of inertia of a body is numerically equal to twice the kinetic energy of the body?

Solution

Kinetic space Energy space of space the space body comma space straight K. straight E space equals space 1 half space straight I space straight omega squared space That space is comma space 2 space straight K. straight E space equals space straight I space straight omega squared

Therefore, when the body revolves with angular velocity 1 rad/s, moment of inertia of a body is numerically equal to twice the kinetic energy of the body.
