The free-body diagram of a box subjected to forces is shown in Figure 8. 13. Because we are concerned about only the horizontal motion, the forces in the vertical direction have been omitted.

(a) What is the direction of the change in the momentum of the box?

(b) If the box is at rest before the forces shown in the diagram are exerted on it, what is the direction of its momentum once the forces are exerted?

Data from Figure 8.13
