Question

Figure 5.7 n f F w 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/s^2 1.1 m/s^2 2.2 m/s^2 1.7 m/s^2 zero
