A flywheel is brought from rest up to a speed of 1500 rpm in 1 minute. What is the average angular acceleration, alpha?

$\omega = \omega_o + \alpha t$

$1500 = 0 + \alpha (1)$

$\alpha = 1500 ~ \text{rev/min}^2$

$\alpha = 1500 ~ \dfrac{\text{rev}}{\text{min}^2} \times \dfrac{2\pi ~ \text{rad}}{\text{rev}} \times \left( \dfrac{1 ~ \text{min}}{60 ~ \text{sec}} \right)^2$

$\alpha = 2.62 ~ \text{rad/sec}^2$
