Question 576: Centre of Mass and Rotational Motion

Question

The moment of inertia of a body about the given axis, rotating with angular velocity 1 rad/s is numerically equal to 'P' times its rotational kinetic energy. The value of 'P' is

Accepted Answer

The angular velocity
$$\begin{aligned}
\omega & =1 \mathrm{~rad} / \mathrm{s} \
I & =P \cdot\left(\frac{1}{2} \mathrm{I} \omega^2ight) \
1 & =\mathrm{P} \cdot \frac{1}{2} \cdot 1 \
	herefore \quad P & =2
\end{aligned}$$
