Dario, a prep cook at an Italian restaurant, spins a salad spinner and observes that it rotates with constant speed 20.0 times in 5.00 seconds and then stops spinning it. The salad spinner rotates 6.00 more times before it comes to rest. Assume that the spinner slows down with constant angular acceleration. ▸

Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.

Follow-up Question
![### Problem Description
Dario, a prep cook at an Italian restaurant, spins a salad spinner and observes that it rotates with a constant speed of 20.0 times in 5.00 seconds. After letting go, the salad spinner rotates an additional 6.00 more times before it comes to rest. Assume that the spinner slows down with constant angular acceleration.
### Part A
**Question:**
What is the magnitude of the angular acceleration of the salad spinner as it slows down?
**Express your answer numerically in radians per second per second.**
**Solution:**
The angular acceleration \( \alpha \) is given as:
\[ \alpha = 8.38 \, \text{radians/s}^2 \]
**Status:** Correct
### Part B
**Question:**
How long does it take for the salad spinner to come to rest?
**Express your answer numerically in seconds.**
**Answer Box:**
- Symbols and template options are available for input.](https://content.bartleby.com/qna-images/question/3dae5a27-a228-455d-8cc9-f5b577430088/b43f85e3-27b8-4924-9eca-09ace3eae59c/l6rqeug_processed.png)
