Problem: A cup of coffee is on a table in an airplane flying at a constant altitude and a constant velocity. The coefficient of static friction between the cup and the table is 0.420. Suddenly, the plane accelerates forward, its altitude remaining constant.
Part A: What is the maximum acceleration that the plane can have without the cup sliding backward on the table?
I need help to find the maximum acceleration that the plane can have without the cup sliding backward on the table and use g = 9.81 m/s2.
