Homework Statement
A glass of orange juice is on the floor of a subway car traveling along a straight path at constant velocity. The coefficient of static friction between the glass and the floor is 0.32. The subway suddenly accelerates forward. What is the maximum acceleration that the subway car can have without the orange juice sliding backward on the floor
Homework Equations
Fs = μ FN
The Attempt at a Solution
So we want the juice to stay still. So the FN x μ cannot become equal or greater than Fs, correct? How would we approach this problem without a mass given for the juice?
