Problem 2: Consider two blocks connected by a massless cable. The masses of blocks A and B are må and m²

respectively. The coefficient of kinetic friction between both blocks and the inclined plane is uk = 0.1. The

coordinates X₁ and x₂ measure the displacements of the two blocks such that x₁ = x₂ = 0 when the system is at rest.

Find a single differential equation of motion for the system in coordinate x₁. Assume ideal pulleys.
