Calculating Final Angular Speed in Rotational Motion
A rotating disc has an initial angular speed of \(5.0\,\text{rad s}^{-1}\). It undergoes a constant angular acceleration of \(2.0\,\text{rad s}^{-2}\) over an angular displacement of \(30.0\,\text{rad}\). Using the rotational kinematic equation \(\omega_f^2 = \omega_i^2 + 2\alpha\Delta\theta\), calculate the final angular speed \(\omega_f\) of the disc. Show your calculation steps and state your answer with appropriate […]
