Here are the calculations for the problems. Part (b) - Truck and Trailer (i) Acceleration of the Truck and the trailer Step 1: Calculate the total mass of the system. M = m_A + m_B = 1000 kg + 3000 kg = 4000 kg Step 2: Calculate the net force acting on the system. The net force is the force exerted by the truck minus the total frictional forces. F_net = F_truck - F_fA - F_fB F_net = 8000 N - 1000 N - 2000 N = 5000 N Step 3: Calculate the acceleration using Newton's second law (F_net = M a). a = F_netM = 50
