When Crates A and B of mass ma = 38 kg and mB = 74 kg are released from rest, Crate A moves to the right on a rough surface (µk = 0.2 ). The force P = 18 Newtons is always acting on Crate B. The linear spring has a stiffness of k = 480 N and is initially stretched 0.5 meters before the system is released from rest. m Neglect the mass of the pulleys and cables and neglect friction in the pulley bearings. Determine the work done by the external force P (in Joules) when Crate A has moved a distance of 0.5 meters to the right.
