Thank you! I actually don't have any calculations, I'm stuck. I tried writing the acceleration as:
\alpha = \omega / 10 per revolution
And then use
\theta = 10 revs + \omega *t +1/2 * \omega/10 t^{2}
t = (3\omega-\omega) / \omega/10
But I just end up confusing myself, because...
Homework Statement
A disk is under constant angular acceleration \alpha. When it starts from rest it takes 10 revolutions before it reaches angular velocity \omega. How many additional revolutions does it take to accelerate the disk further to an angular velocity of 3\omega?The Attempt at a...
