1. ### Angular Acceleration help

thank you dzza...finally got the right answer. i don't think i understood exactly what information i had. i misinterpreted the 20 rev/min as final velocity. thank you very much!
2. ### Angular Acceleration help

when i use that equation, i end up with .333. i'm doing (20rad/s-0rad/s)/60s = 0.333 ??? The answer needs to be in rev/min^2 and I don't know how to get the answer in the form that they want it. If i double the amount that I have, I'll have the right answer, but I don't understand why.
3. ### Angular Acceleration help

This problem states: A human centrifuge takes 1.0 min to turn through 20 complete revolutions before reaching final speed. They are asking for angular acceleration (a) and angular speed in rpm (b). The answer to a is 40 rev/min^2 The answer to b is 40 rev/min -I'm have the formulas for...
