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.
