(N/A) In rotational motion, the power $(P)$ delivered by a torque $(\tau)$ to a rotating body with angular velocity $(\omega)$ is given by the formula:
$P = \tau \cdot \omega$
Where:
$P$ is the power in Watts $(W)$,
$\tau$ is the torque in Newton-meters $(N \cdot m)$,
$\omega$ is the angular velocity in radians per second $(rad/s)$.
The angular momentum $(L)$ of a rigid body rotating about a fixed axis with moment of inertia $(I)$ and angular velocity $(\omega)$ is given by the formula:
$L = I \cdot \omega$
Where:
$L$ is the angular momentum in kilogram-meters squared per second $(kg \cdot m^2/s)$,
$I$ is the moment of inertia in kilogram-meters squared $(kg \cdot m^2)$,
$\omega$ is the angular velocity in radians per second $(rad/s)$.

$A$ cord of negligible mass is wound around the rim of a wheel supported by spokes with negligible mass. The mass of the wheel is $10 \ kg$ and the radius is $10 \ cm$. It can rotate freely without any friction. Initially,the wheel is at rest. If a steady pull of $20 \ N$ is applied on the cord,the angular velocity (in $rad/s$) of the wheel,after the cord is unwound by $1 \ m$,would be:

$A$ thin meter rod is placed with one end on the ground. It is allowed to fall such that the contact point remains fixed. Find the velocity of the upper end when it hits the ground.
