A 50 kg box is sitting on a level surface. The coefficient of static friction is 0.30. A horizontal push of 80 N is applied to the box. What is the resulting friction force (N) upon the box? (Careful. Note that the net force upon the box is 0.)

Step 1
The net force on the box is 0, which means that the force of friction must be equal in magnitude and opposite in direction to the applied force. Show more…

When a horizontal force of 125 N is applied to a 15.0-kg box, the box slides on a level floor, opposed by a force of kinetic friction of 70 N. What is the magnitude of the acceleration of the box?
