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 angular acceleration but most of them won't work b/c I don't have any velocity attached to this problem.

I don't know how to set the problem up to receive the right answer. I've tried converting from radians to rev/min^2 and end up with the wrong answer every time. This isn't a very difficult problem but I don't understand how to set the problem up to find the right answer.

I end up with 2.09 rad/s but that answer doesn't take me in the right direction (at least I don't think so).

Thanks in advance,

Dusty
