Figure 5.7




A box with weight 40 N is on a rough horizontal surface. An external force F is applied horizontally to the box.  A normal force and a friction force are also present, denoted by n and f.  A force diagram, showing the four forces that act on the box, is shown in Figure 5.7. When force F equals 8.8 N, the box is in motion at constant velocity. The box decelerates when force F is removed. The magnitude of the acceleration of the box is closest to:

• 0.55 m/s2

• 1.7 m/s2

• 2.2 m/s2

• zero

• 1.1 m/s2
