Ohanian's signature approach: Always isolate the body, draw all contact and long-range forces, then apply $\sum F_x = ma_x$, $\sum F_y = ma_y$. : Constraint equations (e.g., $a_block = a_pulley$) tie accelerations in compound systems.
$\omega = \sqrtg/L$ — surprisingly independent of mass. --- Fisica Para Ingenieria Y Ciencias Ohanian Vol.1 3ed Pdf
