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?
