The initial angular velocity and the angular acceleration of four rotating objects at the same instant in time are listed in the table that follows. For each of the objects (a), (b), (c), and (d), determine the final angular speed after an elapsed time of 2.0 s.
Initial angular velocity v0 _____________________Angular acceleration α
(a) +12 rad/s .................................................... +3.0 rad/s2
(b) +12 rad/s .................................................... -3.0 rad/s2
(c) -12 rad/s .................................................... +3.0 rad/s2
(d) -12 rad/s .................................................... -3.0 rad/s2
