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. == Ans.: a=0.22 m/s² ; 20.3 N B H A 30° P=40 N Figure 3

3. Two blocks, mı = 9 kg and mɔ = 15 kg, are connected by a light string that passes over a frictionless pulley as shown in the figure. The first block lies on a horizontal surface and is connected to a spring with 45 N/m force constant. The system is released from rest when the spring is at equilibrium (unstretched). If the kinetic friction between mị and the surface is 0.20, calculate: (a) the distance h which the hanging block falls before coming to rest. (b) the work done by the spring on mị (c) the work done by the string on m || k

Learning Goal: To use the equations of equilibrium to analyze a system containing a wedge and to determine the necessary applied force to introduce motion into the system. The crate shown is held against wedge B by a spring. The spring is 94.0% of its original uncompressed length 1 = 3.00 m, and the spring constant is given as k = 1650 N/m. The coefficient of static friction at all contacting surfaces is μs = 0.100. The mass of the crate is m = 25.0 kg . The angle is 0 = 14.0°. Neglect the mass of the wedge.
