Answer:
5.74s
Explanation:
We can first solve for the initial angular velocity using the following formula
Where 
is the final angular velocity, 
is the angular acceleration and 
is the angular displacement
So for the wheel to get from 22.4 to -22.4 with angular acceleration of -7.8 then the time it takes must be
