Just checking to see fi I did the math right:(adsbygoogle = window.adsbygoogle || []).push({});

During the spin-dry cycle of a wash, the motor slows down from 95 rad/s to 30 rad/s while turning the drum through an angle of 402 radians. What is the magnitude of the angular acceleration of the motor?

= 1/2(Wo + W)t

402 = 1/2(95 + 30)t

402 = 62.5t

6.4 = t

ang. accel. = W - Wo / t - to

= 30 - 95 / 6.4

= 10 rad/s^2
