Object A is on the top of a table and object B is hanging from a cord connected to object A over a pulley. Suppose object A has mass 4.0 kg and object B has mass 2.0 kg. The coefficient of kinetic friction between object A and the table is 0.2.  The coefficient of static friction between object A and the table is 0.4.  Draw a free-body diagram for object A and another free-body diagram for object B.  Find the acceleration of object B (magnitude and direction), and the tension in the cord.

Cart 1 has a mass of 20.0 kg, cart 2 has a mass of 10.0 kg, and Cart 3 has a mass of 15.0 kg. Coefficient of Kinetic friction is 0.10. A third cord, which pulls on cart 1 and is at an angle of 23° above the horizontal, has a tension of magnitude 150 N.(hint: FN of cart 1 is NOT equal with Fg). Draw FBD for each cart. a) Determine the magnitude of the acceleration of the carts. b) Determine the magnitude of the tension (T2) in the cord between m3 and m2. c) Determine the magnitude of the tension (T1) in the cord between m2 and m1

Two blocks on a horizontal, frictionless surface are in contact with one another, pushed by a horizontal force of magnitude P as shown below with m₁ = 3 kg, m₂ = 10 kg, and P = 8 N. Find the magnitude of the contact force F21 that block 2 exerts on block 1. P M2 m1
