Figure 5.7




A box with weight 74 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 4.8 N, the box is in motion at constant velocity. When force F equals 6.24 N, the acceleration of the box is closest to:

• 0.23 m/s2

• 0.29 m/s2

• 0.26 m/s2

• 0.19 m/s2

• 0.32 m/s2
