An electric motor rotating a workshop grinding wheel at 1.12 x 102 rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 1.90 rad/s². (a) How long does it take the grinding wheel to stop? S (b) Through how many radians has the wheel turned during the time interval found in part (a)? rad
