Quizplus · Accepted Answer

The formula for angular velocity is $\omega = \frac{\theta}{t}$. Substituting $\theta = \frac{\pi}{10}$ and $t = 7$ gives $\omega = \frac{\pi/10}{7} = \frac{\pi}{70}$ radians per second.

Use the Formula ω=θt\omega = \frac { \theta } { t }ω=tθ​

Use the Formula $\omega = \frac { \theta } { t }$
