nursing AIIMS BSc Nursing 2025 Mock Test Series Physics Rotational Motion Work and Rotational Kinetic Energy
A body of mass m is at height h. When it reaches the ground, it has pure rotational kinetic energy. Find its angular speed at ground. (given that moment of inertia of body is I)
1
\( \omega = \sqrt{mgh \over I}\)
2
\( \omega = \sqrt{2mgh \over I}\)
3
\( \omega = \sqrt{mgh \over2 I}\)
4
\(\omega = \sqrt { mgh I }\)
