2022 F = ma Exam A — Question 12

A pulley is constructed by attaching two concentric cylinders, with the larger cylinder having twice the radius. Ropes are wrapped around both cylinders, a mass m is hung from each rope, and the system is released from rest. m m Neglect the masses of the cylinders and ropes. Each mass experiences both a gravitational and a tension force. If the net force experienced by the left mass is F1 , and the net force experienced by the right mass is F2 , what is the ratio F2 /F1 ? — Source: Question 12, 2022 F = ma Exam A, © 2022 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
