Moderate# Angular Momentum and Atwood machines

APPHMC-NNY4ZM

For the Atwood machine depicted above, the mass of the pulley wheel is $50g$ , $r= 25 cm$, $R=50cm$, $m_1=125g$ and $m_2=150g$. The mass of the rope and frictional effects are negligible.

If the pulley wheel starts from rest, what is the angular momentum of the pulley wheel after 5.0s?
