The blades of a fan rotate clockwise at −225 rad/s at medium speed, and −355 rad/s at high speed. If it takes 3.05 seconds to get from medium to high speed, what is the average angular acceleration of the fan blades during this time?(adsbygoogle = window.adsbygoogle || []).push({});

Is the answer

-(355-225)/3.05

= 42.6 rad/s^2

Please work it out and tell me if I did this correctly
