In the free-body diagram, the magnitude of the normal force is 35 N, the friction force is 15 N, and the net force is 70 N. What is the magnitude of the applied force? Explain how you came to your answer in one to two sentences.
1 answer
The magnitude of the applied force is 50 N. This can be determined by subtracting the sum of the normal force and the friction force from the net force, since the applied force is the only remaining force acting on the object.
