# Normal Force, Static and Kinetic Frictional Forces For A Cup Of Coffee

A cup of coffee is setting on a table in a airplane that is flying at a constant altitude and a constant velocity. The coefficient of the static friction between the cup and the table is 0.30. Suddenly, the plane accelerates, its altitude remaining constant. What is the maximum acceleration that the plane can have without the cup sliding backward on the table?
