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 4 s. Initial angular velocity wo Angular acceleration a 1/?
(a) (b) (c) (d) Initial angular velocity wo +31.0 rad/s (a) Final angular speed = +31.0 rad/s -31.0 rad/s -31.0 rad/s i1012 Angular acceleration a +6.0 rad/s² -6.0 rad/s² +6.0 rad/s² -6.0 rad/s² rad/s 0
(a) Final angular speed = (b) Final angular speed= (c) Final angular speed = (d) Final angular speed Apt 4012 -4012 rad/s rad/s rad/s rad/s 0 O
