Block A in the figure weighs 1.16 N and block B weighs 3.62 N. The coefficient of kinetic friction between all surfaces is 0.293. Find the magnitude of the horizontal force F necessary to drag block B to the left at constant speed if A rests on B and moves with it (figure (a)). Find the magnitude of the horizontal force F necessary to drag block B to the left at constant speed if A is held at rest (figure (b)).
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.
