(a)
The
(a)
Answer to Problem 2PP
The angular displacement in 3 minutes is
Explanation of Solution
Given:
Time taken by a rotating toy to complete one counterclockwise rotation in 1 min
Formula used:
One revolution is equivalent to
Calculation:
Angular displacement in 1 min is,
So, the angular displacement in 3 min is,
Conclusion:
Therefore, the angular displacement in 3 min is
(b)
The
(b)
Answer to Problem 2PP
The angular velocity of toy in rad/min is 6.28 rad/min
Explanation of Solution
Given:
Time taken by a rotating toy to complete one counterclockwise rotation in 1 min
Formula used:
Angular velocity is,
Calculation:
Angular velocity,
Conclusion:
Therefore, angular velocity of toy is6.28 rad/min
(c)
To identify: Whether the toy
(c)
Answer to Problem 2PP
The angular acceleration of toy is negative.
Explanation of Solution
Given:
Time taken by a rotating toy to complete one counterclockwise rotation in 1 min.
Formula:
Angular acceleration is,
Calculation:
If the toy is turned off, the angular velocity will reduce to 0. Final angular velocity = 0 rad/min
So, angular acceleration will be,
Now,
Conclusion:
Therefore,if toy is turned off then there will be a decrease in its angular velocity. So angular acceleration of toy is negative.
