Answer to Problem 50A
Zero
Explanation of Solution
Introduction:
The constant rate of revolution of a toy means that it covers a fixed angular distance in a time.
If in a time, the toy covers a fixed distance or undergoes fixed revolutions in a minute, then its
Now, if the angular velocity of the toy is constant then its angular acceleration will be zero since angular acceleration is the time rate change of angular velocity.
Conclusion:
Hence, the angular acceleration of a toy is zero if it rotates at a constant rate of
