Calculate the rotational inertia of a wheel that has akinetic
energy of 24,400 j when rotating at 566 rev/min.

J = 14.4 kg*m^2

Explanation:

Assuming that the wheel is not moving anywhere, and the kinetic energy is only due to rotation:

Ek = 1/2 * J * w^2

J = 2 * Ek / (w^2)

We need the angular speed in rad / s

566 rev/min * (1 min/ 60 s) * (2π rad / rev) = 58.22 rad/s

Then:

J = 2 * 24400 / (58.22^2) = 14.4 kg*m^2

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
