(C) The impulse $J$ applied at one end provides both linear and angular momentum to the system.$1$. Linear impulse equation: $J = M_{total} v_{cm} \Rightarrow MV = (2M) v_{cm} \Rightarrow v_{cm} = \frac{V}{2}$.$2$. Angular impulse equation about the center of mass $(COM)$: $J \times r = I_{cm} \omega$.Here,$r = \frac{L}{2}$ and $I_{cm} = M(\frac{L}{2})^2 + M(\frac{L}{2})^2 = \frac{ML^2}{2}$.Substituting the values: $(MV) \times \frac{L}{2} = (\frac{ML^2}{2}) \omega$.Solving for $\omega$: $\frac{MVL}{2} = \frac{ML^2 \omega}{2} \Rightarrow \omega = \frac{V}{L}$.

$A$ massless rod of length $2l$ has equal point masses $m$ attached to its two ends as shown in the figure. The rod is rotating about an axis passing through its centre and making an angle $\alpha$ with the axis. The magnitude of the rate of change of angular momentum of the rod,i.e.,$\left|\frac{dL}{dt}\right|$,is equal to:
