Question:medium

The moment of inertia of a body about a given axis is \(1.2\ \text{kg·m}^2\). To produce a rotational kinetic energy of \(1500\ \text{J}\) an angular acceleration of \(25\ \text{rad/s}^2\) must be applied for

Show Hint

Rotational KE = \(\frac{1}{2}I\omega^2\) is analogous to translational KE = \(\frac{1}{2}mv^2\).
