Block A in the figure is sliding down the incline. The rope is massless, and the massless pulley turns on frictionless bearings, but the surface is not frictionless. The rope and the pulley are among the interacting objects, but you will have to decide if they are part of the system.
A: Draw a free-body diagram for the block A.
B: Draw a free-body diagram for the block B.
The location and orientation of the vectors will be graded. The length of the vectors will not be graded.
