Problem

A turntable rotates clockwise at

15\,\text{rev min}^{-1}

. It is subjected to a constant angular acceleration of

30\,\text{rev min}^{-2}

acting anticlockwise. How many complete revolutions will the turntable make before coming to rest? (Take clockwise rotation as negative.) a)

7.50\,\text{rev}

3.75\,\text{rev}

11.25\,\text{rev}

15.0\,\text{rev}
