Physics - Rotation Question with Solution | TestHub

Here, a particle moves along a circular path of radius $r$ with uniform speed $v$. Thus, the angular velocity is: $\omega =\frac{v}{r}$ The angle described by the radius vector is: $\theta =\omega t$ For $t=1\mathrm{s}$, $\theta =\omega =\frac{v}{r}$
