Problem

A turntable is spinning with an initial angular speed of 5.0 rad s⁻¹. Its angular acceleration is 2.0 rad s⁻² in the same direction. What will be its angular speed after it has turned through 8.0 rad? (a) 21 rad s−121\,\text{rad}\,\text{s}^{-1} (b) 5.1 rad s−15.1\,\text{rad}\,\text{s}^{-1} (c) 7.6 rad s−17.6\,\text{rad}\,\text{s}^{-1} (d) 6.4 rad s−16.4\,\text{rad}\,\text{s}^{-1}
