The
Answer to Problem 57A
Explanation of Solution
Given:
Initial
Final angular velocity of the propeller,
Time taken,
Formula used:
The angular acceleration is:
Where,
Calculation:
Initial angular velocity of the propeller is
Final angular velocity of the propeller is
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 propeller is
