Question

The moment of inertia of a particle
about an axis of rotation is
0.2 kg m². If the angular momentum
of the particle about the axis is
0.4kg m²/s, then what is the rotational
Kinetic energy of the particles​

Answer 1

Answer:

The rotational kinetic energy is the kinetic energy of rotation of a rotating rigid body or system of particles, and is given by K=12Iω2 K = 1 2 I ω 2 , where I is the moment of inertia, or “rotational mass” of the rigid body or system of particles.
