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

To find the magnitude of the applied force, we can use Newton's second law which states that the net force equals mass times acceleration. Since it is given that the net force is 70 N and the friction force is 15 N, the applied force must be 70 N + 15 N = 85 N.
