Three boxes rest side-by-side on a smooth, horizontal floor. Their masses are 5.0-kg, 3.0-kg, and 2.0-kg, with the 3.0-kg mass in the center

A force of 50 N pushes on the 5.0-kg mass, which pushes against the other two masses. (a) Draw the free-body diagrams for each of the masses. (b) What is the contact force between the 5.0-kg mass and the 3.0-kg mass? (c) What is the contact force between the 3.0-kg and the 2.0-kg mass?
