A 3.0-kg and a 5.0-kg box rest side-by-side on a smooth, level floor. A horizontal force of 32 N is exerted on the 5.0-kg box pushing it against the 3.0-kg box, and, as a result, both boxes slide along the floor
How hard do the two boxes push against each other? A) 12 N B) 20 N C) 24 N D) 32 N E) 0 N
