A student applies a 200 N force at an angle 60° below the horizontal to a 20 kg box initially at rest on a level surface. The applied force causes the box to accelerate. The coefficient of kinetic friction between the box and the surface is 0.25. What is the normal force on the box? What is the friction force on the box? What is the box’s acceleration?
