The inital 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.

Step 1

**Given information:**

Initial angular velocity of object 1 (ω_{i-1}) = +22 rad/s

Angular acceleration of object 1 (α_{1}) = +5 rad/s^{2}

Initial angular velocity of object 2 (ω_{i-2}) = +22 rad/s

Angular acceleration of object 2 (α_{2}) = -5 rad/s^{2}

Initial angular velocity of object 3 (ω_{i-3}) = -22 rad/s

Angular acceleration of object 3 (α_{3}) = +5 rad/s^{2}

Initial angular velocity of object 4 (ω_{i-4}) = -22 rad/s

Angular acceleration of object 4 (α_{4}) = -5 rad/s^{2}

Angular velocity of each object after time (t) = 4 s

Step 2

Angular velocity (ωf-1) of object 1 after time (t) is given f...
