Blocks A (mass 2kg), B(mass 5 kg), and C (mass 15 kg) are connected by two cables as shown. The system is released from rest. First show that the blocks will move (hint: right at the limit of static equilibrium, A is about to move up, B to the right, and C'down), then find the acceleration of the blocks and the tensions in the cables. The coefficient of static and kinetic friction between block B and the surface are both...
