A boxed cake is placed in the trunk of a car to be delivered to a birthday party. The coefficient of static friction is 0.15 and for kinetic friction is 0.11. What is the minimum 0-60 mph time that the car can accelerate and keep the box from sliding? In other words, what is the shortest time for the driver to accelerate from a stop up to 60 mph and not have the box slide back...
