I feel really dumb, as this should be incredibly easy to figure out, but I keep getting the wrong answers. I am including the book's data so I can figure out how this needs to be done and then plug in my own values.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Pilots can be tested for the stresses of flying high-speed jets in a whirling "human centrifuge," which takes 1.0 min to turn through 20 complete revolutions before reaching its final speed.

What is its angular acceleration (assumed constant) (in rev/min^2) and its angular velocity in rpm?

2. Relevant equations

Code (Text):

\theta (t) = \theta_0 +\omega_0t + \frac{1}{2}\alpha t^2

\omega (t) = \omega_0 + \alpha t.

[\CODE]

[b]3. The attempt at a solution[/b]

I have tried finding the frequency and then multiplying it by 2\pi, but I don't get the right answer. The book's values are:

Ang. Acc = 40 rev/min^2

Ang. Vel = 40 rpm
