Chapter 6, Problem 79P

SSM Block A in Fig. 6-56 has mass m_A = 4.0 kg, and block B has mass m_B = 2.0 kg. The coefficient of kinetic friction between block B and the horizontal plane is µ_k = 0.50. The inclined plane is frictionless and at angle θ = 30°. The pulley serves only to change the direction of the cord connecting the blocks. The cord has negligible mass. Find (a) the tension in the cord and (b) the magnitude of the acceleration of the blocks.

Chapter 6, Problem 79P, SSM Block A in Fig. 6-56 has mass mA = 4.0 kg, and block B has mass mB = 2.0 kg. The coefficient of
