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. Part A 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. ▸ View Available Hint(s) a = 8.38 radians/s² Submit ✓ Correct Part B Previous Answers How long does it take for the salad spinner to come to rest?

I would like the solution for this problem. Not sure how to get the values out of the info I got.

I've gone through like 4 pages trying to figure this out and i keep getting nonsensical answers.  Help would be greatly appreciated!
