Question 1 of 5
MEDIUMTwo blocks of masses 3 kg and 5 kg are connected by a light string passing over a frictionless pulley. The 5 kg block rests on a rough horizontal surface with coefficient of friction μ = 0.4, while the 3 kg block hangs vertically. The acceleration of the system is (g = 10 m/s²):
