1. DETAILS MY NOTES ASK YOUR TEACHER An electric motor rotating a workshop grinding wheel at 1.02 X 102 rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 2.08 rad/s2. (a) How long does it take the grinding wheel to stop? (b) Through how many radians has the wheel turned during the time interval found in part (a)? rad 2. . DETAILS MY NOTES ASK YOUR TEACHER A cylinder of mass 14.0 kg rolls without slipping on a horizontal surface. At a certain instant its center of mass has a speed of 13.0 m/s. (a) Determine the translational kinetic energy of its center of mass. (b) Determine the rotational kinetic energy about its center of mass. (c) Determine its total energy.
