A cup of coffee of mass 250 grams sits on a table in a train carriage?

Question

The train accelerates at 1.2 ms2 out of a station. 

a- draw the forces acting on the cup of coffee 
b- if the cup does not slip, find the value of the friction force acting on the cup of coffee 
c-if the cup is just about to slip, find the coefficient of friction between the cup and the surface of the table

Answer

This requires drawing pictures, and we can't draw pictures here. You'll just have to study the book and learn how to do this. Physics is largely a matter of imagination.
