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 s.    Initial angular velocity ω0     Angular acceleration α   (a)  +17.0 rad/s +5.0 rad/s2  (b)  +17.0 rad/s -5.0 rad/s2  (c)  -17.0 rad/s +5.0 rad/s2  (d)  -17.0 rad/s -5.0 rad/s2

The angular position of a rotating object as a function of time is given below: e = 3.113-2.5t2 +4.7t+d Here e is in units of radians and t is in units of seconds and d is constant. Determine the instantaneous angular acceleration of the object at t=2.9s. Express your answer in units of rad/s using one decimal place.
