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.

If the system isn't accelerating, then you are better off choosing the coordinate system with the most vectors along the coordinate axes. But now you are gaing to ignore that advice.…

An 8.00 kg crate sits on an inclined plane that is inclined at 33.0 above the horizontal. The coefficient of kinetic friction between the crate and the surface of the plane is 0.300. A constant horizontal force F = 28.0 N is applied to the crate (Figure 1), and the crate moves down the plane.
