Problem

A warehouse worker applies a force F to accelerate two crates with the same mass, m, start subscript, A, end subscript and m, start subscript, B, end subscript, to the right along a rough floor.
Two crates of the same size sit side by side on a horizontal surface, in contact with one another. The crate on the left is labeled M sub A. The crate on the right is labeled M sub B. An arrow labeled F is to the left of box M sub A. The arrow points toward the right, touching the crate.
Which is the correct relationship between the applied force F acting on m, start subscript, A, end subscript and the force m, start subscript, A, end subscript exerts on m, start subscript, B, end subscript?
