High school Physics question

Question

A 10 kg box is pulled by 15 Newton force. It accelerates at 2m/s/s. Determine the force of friction

Answer 1

A free body diagram would help you solve this problem. Drawing the forces acting on this box would allow you to see that the 15-Newton force is being opposed by the Friction force. You can then write an equation to help you solve for the friction force. ΣF = ma The challenge for these types of problems is practicing the free body diagrams. When you draw the force vectors, you can then see the tug-of-war that is going on. This enables you to fill in the Forces that are being summed up ΣF.
