the coefficient of static friction between the coffee cup and the roof of a car is 0.28, If the maximum acceleration the car can have without causing a cup of coffee (on the top of the car) to slide is 2.7 m/s^.
What is the smallest amount of time in which the person can accelerate the car from rest to 19 and still keep the coffee cup on the roof?

What speed dimensions are supposed to follow the number V = 19?
If the acceleration cannot exceed a = 2.7 m/s^2, the time to acclerate to velocity V must be greater than
V/a.
You do not need to know the coefficient of friction to answer this question. They threw it in to confuse you.
