This video shows the basics of how to use the static friction and kinetic friction equations when solving physics problems.

Problem Statement:
A 2 kg book is placed on a flat surface and pushed to the right with 5N of force. Assume the coefficient of static friction is 0.3 and the coefficient of kinetic friction is 0.2. What is the box’s acceleration? What is the box's acceleration if 12N is used?
