3. Figure 3 shows a system consisting of wedge A and block B connected by an inextensible cable that runs around three pulleys. The mass of A is 12 kg and the mass of B is 3 kg. Due to the application of the constant force P = 40 N, wedge A moves to the right causing block B to move up on the wedge. The friction between the wedge A and the horizontal surface is negligible. The kinetic coefficient of friction between A and B is μ = 0.25. If the system is originally at rest (before P was applied), determine the accelerations of wedge A and block B immediately after P is applied. Also, calculate the tension in the cable.

When Crates A and B of mass ma = 31 kg and mB = 78 kg are released from rest, Crate A moves to the right on a rough surface (u = 0.4 ). The force P = 20 Newtons is always acting on Crate B. The linear spring has a stiffness of k = 490 N and is initially stretched 0.4 meters before the system is released from rest. Neglect the mass of the pulleys and cables and neglect friction in the pulley bearings. Determine the work done by the weight of Crate B (in Joules) when Crate A has moved a distance of 0.8 meters to the right. Consider g = 10 m. 82 B
