(a) A large rotating flywheel uniformly increases in angular speed from rest to 0.210 rev/s in 26.0 s. What is its angular acceleration in radians per second per second? rad/s2   (b) The same flywheel again starts from rest and accelerates uniformly in the same time interval, but now the angular acceleration is double that found in part (a). What is true about the final angular speed?       a. It is the same as the value given in part (a).       b. It is half the value given in part (a).            c. It is double the value given in part (a).         d. It is quadruple the value given in part (a).
