Question 1162033: Please help! (multiple choice)
A box with weight 48 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. When force F equals 8.4 N, the box is in motion at constant velocity. When force F equals 10.92 N, the acceleration of the box is closest to:
A) 0.70 m/s2
B) 0.51 m/s2
C) 0.79 m/s2
D) 0.61 m/s2
E) 0.88 m/s2
Hint: Since Force equals mass times acceleration, if acceleration is zero, net force must be zero. Hence, the applied force and the friction force must be equal when the applied force is 8.4 N. Then then net force when the applied force is 10.92 N, must be 2.52 N.
