Answer:
The angular acceleration and angular displacement is and 31.34 rad .
Explanation:
Given :
Initial linear speed , u = 9.8 m/s .
Final speed , v = 2.2 m/s .
Time taken , t = 3.4 s .
Radius of wheel , r = 0.65 m .
So , decelerates of wheel is given by :
Therefore , angular velocity is given by :
Now , linear displacement is :
Therefore , angular displacement is :
Hence , this is the required solution .
