A windmill blade with a rotational inertia of \(6.0\,\text{kg}\cdot\text{m}^2\) has an initial angular velocity of \(8\,\text{rad/s}\) in the clockwise direction. It is then given an angular acceleration of \(4\,\text{rad/s}^2\) in the clockwise direction for \(10\,\text{seconds}\). What is the change in rotational kinetic energy of the blade over this time interval?
