Three boxes, A, B, and C, are placed on a frictionless surface as shown in the diagram below. If you push on box A with a force of 8.25 N, find the contact force (in N) between each pair of boxes. Here mA = 7.20 kg, mB = 4.30 kg, and mC = 1.50 kg. contact force between A and B x What is the acceleration of the three box system due to the applied force? How much force is applied to boxes B and C by box A? N contact force between B and C X How much force does box B apply to Box C? N The three diagrams below show a block of mass m being pulled or pushed at constant acceleration ax along a table with a force P. The coefficient of kinetic friction is pk. What is the friction force in each case? Give your answer in terms of the pushing force P, ax, m, and the angle 9.
