6) A grindstone (Fig. 10-8) rotates at constant angular acceleration a=0.35 rad/s² . At time t = 0, it has an angular velocity of wo= -4.6 rad/sand a reference line on it is horizontal, at the angular position = 0 We measure rotation by using this reference line. Clockwise = negative Counterclockwise = positive Axis -Reference line Zero angular position Figure 10-8 A grindstone. At t=0 the reference line (which we imagine to be marked on the stone) is horizontal. (a) At what time after t=0 is the reference line at the angular position0 = 5.0 rev?
