A block of mass 1.0 kg sits on top of one of mass 2.0 kg as pictured. The blocks have a coefficient of kinetic friction µk = 0.35 between them. There is no friction between the 2.0 kg block and the surface beneath it. Find the acceleration of the 2.0 kg bock, and the strength of the tension in the rope connecting the two blocks. Treat the ropes as massless.

**Written Challenge Problem, Newton’s Third Law:**

A block of mass 1.0 kg sits on top of one of mass 2.0 kg as pictured. The blocks have a coefficient of kinetic friction μₖ = 0.35 between them. There is no friction between the 2.0 kg block and the surface beneath it. Find the acceleration of the 2.0 kg block, and the strength of the tension in the rope connecting the two blocks. Treat the ropes as massless.

**Diagram Explanation:**

The diagram shows two stacked blocks: the top block has a mass of 1.0 kg, and the bottom block has a mass of 2.0 kg. A rope is connected to the 1.0 kg block and is being pulled horizontally with a force of 20 N to the right. The surface on which the 2.0 kg block rests is frictionless.
