Answer:
Angular acceleration, 
Explanation:
It is given that,
Displacement of the rotating wheel, 
Time taken, t = 2.9 s
Initial speed of the wheel, 
Final speed of the wheel, 
Let 
is the angular acceleration of the wheel. Using the third equation of kinematics to find it as :
So, the angular acceleration of the wheel is 
. Hence, this is the required solution.
