that passes The figure shows three blocks at rest. Block A, with a mass of 4.5 kg, is on a horizontal tabletop and is connected to block B (which has a mass of 3.2 kg) by a rope around a massless, frictionless pulley. When block C is lifted off block A, block A accelerates to the right and block B accelerates downward. As block A slides to the right, a kinetic frictional force with a magnitude of 20 N acts on block A. Frictionless, massless pulley A 수 B
