An electric motor rotating a workshop grinding wheel at 1.08 x 10 rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 2.06 rad/s? (a) How long does it take the grinding wheel to stop? Note that the time required for the wheel to stop is the same as the time for the wheel to start from rest and reach the given angular speed with the same magnitude angular acceleration, s (6) Through how many radians has the wheel turned during the time interval found in part (a)? It might be helpful to translate this problent into linear variables (a car traveling with an initial speed and then slowing down with a constant negative acceleration), rad Need Help? Pad Master
