Block A in (Figure 1) is heavier than block B and is sliding down the incline. All surfaces
have friction. The rope is massless, and the massless pulley turns on frictionless bearings.
The rope and the pulley are among the interacting objects, but you'll have to decide if
they're part of the system.
