Problem
Block A of mass 2.0 kg rests on a rough horizontal table and is connected by a light string over a frictionless pulley to block B of mass 1.0 kg, which hangs freely. The coefficient of kinetic friction between block A and the table is 0.30, and the system is released from rest. What is the magnitude of the acceleration of the system?
(a) 1.0m/s2
(b) 3.3m/s2
(c) 1.3m/s2
(d) 2.0m/s2
