Question:

Blocks A, B, and C are placed as in Fig. 5.56 and connected by ropes of negligible mass. Both A and B weigh 25.0 N each, and the coefficient of kinetic friction between each block and the surface is 0.35. Block C descends with constant velocity.
(a) Draw two separate free-body diagrams showing the forces acting on A and on B.
(b) Find the tension in the rope connecting blocks A and B.
(c) What is the weight of block C?
(d) If the rope connecting A and B were cut, what would be the acceleration of C?
