Question $(2)$: For the given pulley system assume that the pulley is a uniform solid disc of $M=3\mathrm{.}0kg$ and diameter $40$ cm $.$ If ${}_k=0\mathrm{.}1$ between table and $10$ kg block, and the system is release from rest, follow the diagram

$($Pulley has rotational inertia $I=\frac{1}{2}m{p}_p{R}^2)$

$($i$)$ Draw the free body diagram and derive an expression for the acceleration of the system and calculate tension in the wire on both sides of the pulley

$($ii$)$ What is the torque in the pulley, its angular acceleration?

$($iii$)$ How would your expression and result in part $($i$)$change if pulley was massless?
