The
Answer to Problem 8SSC
Explanation of Solution
Given:
The drum was turning at
It requires
Formula used:
The angular acceleration can be obtained by:
Where
Calculation:
Initial angular velocity of the drum is,
Finally the drum stops, thus
Time taken to stop is,
Then, the angular acceleration will be,
Negative sign shows that the angular velocity decreases with time.
Conclusion:
Thus, angular acceleration of the drum is
