Physics - Rotation Question with Solution | TestHub

Given,

Moment of inertia of body$\left(I\right)=2 \mathrm{kg} {\mathrm{m}}^2$

Rotation of the body in one second$\left(f\right)=2$

We know that,

Angular momentum$\left(L\right)=I\omega$

$L=2\times 2\pi f$

$L=2\times 2\pi \left(2\right)$

$L=8\mathrm{\pi }\mathrm{ }\mathrm{J} \mathrm{s}$
