- Enter the values of the three known variables in the text boxes

- Leave the text box empty for the variable you want to solve for

- Click on the calculate button.

$\omega= \omega_{0} + \alpha t$

$\theta =\omega_{0}t + \frac{1}{2} \alpha t^2$

$\omega ^2 = \omega_{0}^2 + 2\alpha \theta $

- A wheel initially has an angular velocity of 18 rad/s. It has a constant angular acceleration of 2.0 rad/s
^{2}and is slowing at first. What angular displacement before its angular velocity is 18 rad/s in the direction opposite to its initial angular velocity?

- A wheel initially has an angular velocity of 18 rad/s. It has a constant angular acceleration of 2.0 rad/s
^{2}and is speeding up. What will the angular velocity after it rotate an angular displacement of 30 rad?
