What is the angular acceleration of the salad spinner as it comes to rest?

- physics -
**drwls**, Monday, December 7, 2009 at 4:11pmDivide 2 pi x 25 radians by 10 seconds for the initial angular velocity. I get 15.71 rad/s

Divide that angular rate by the time it takes to stop, to calculate the angular deceleration rate.

The time that it takes to stop is 16 pi radians divided by the average angular velocity. I get 6.40 s for that
